# Practice electric charge worksheet answers

Electric field lines are the bridge between electrostatics and circuits. Students learned about Coulomb's Law in the previous lesson and now apply that understanding to the concept of potential difference as seen by electric field lines. During the course of this lesson, student read about electric field lines and look for the rules that govern their formation.

They practice drawing the field lines and determine the relative direction magnitude of electric force that acts on a test charge placed in an electric field. Students write down the problem in their notebooks and complete it. They can use their notes as a resource, as they need the value for an elementary charge and the value for Coulomb's constant to perform the calculation. I give the class a few minutes to work through the problem.

Then I call on a random student to provide the answer, which is 4. I tell them to practice the calculations until they get it correct. The reason for this review is to prepare students for the concept of electric field lines. Coulomb's Law informs one of the strength of an electric force, but the direction is difficult to determine except for the most simple cases.

Electric field lines give us a powerful visual to helps with this. With this worksheet, students define contact force and field force. They also read through the text to determine the rules for electric field lines. The sheet also contains practice problems for field line drawings; students apply the rules of field lines to draw the field lines around different collections of charge. Students work alone and I walk around the room to make sure students are on task and to give support where needed.

After 20 minutes, I use my document camera to show exemplar student work. This power point contains animation that do not work in preview mode.

## Electricity and Circuits Worksheets

The purpose of these notes is to give students a formal definition of electric field lines and test charge as a resource in their notebooks. The next several slides show field lines for various charge configurations.

I want to expose students to several different field line formations, so there is no need to write these samples in their notebooks as this would take too much time. Again, this is a solo activity where students determine the relative magnitude and direction of electric forces on the charges shown in the picture.

This leads to the concept of electric potential and circuits which begin the next lesson. The class finishes with a review of the Test Charge sheet. Again, I collect some student samples to display with my document camera.

I ask students to explain their answers to the rest of the class. The final departing concept has to do with electric potential. We can arrange charge objects to create an electric potential that causes charged objects, such as electrons, to accelerate. Two charge plates change the path of an electron, as seen on the final slides of Electric Field Lines Power Point.

The applications are many, such as a cathode ray tube in older TVs and particle detectors.The electricity continues to travel around to the positive side of the battery. Draw arrows on the picture to show the path of the electricity. Conductors and Insulators A conductor is a material that allows electricity to flow through it. An insulator is a material that electricity cannot flow through.

To determine whether an object is a conductor or insulator, you can build a simple circuit with a battery, light bulb, and three pieces of wire. Complete an electrical home safety inspection of your home, using the checklist found in this the merit badge pamphlet or one approved by your counselor. Discuss what you find with your counselor.

Electricity Choose the best answer for each question. Write the letter on the line. What supplies energy in an electric circuit? Which material is a conductor? Which type of circuit is Circuit A? Qualitative Questions: 1. Draw a picture for each.

Make a list of the materials used at the top. Electricity is a type of energy that can build up in one place or flow from one place to another. When electricity gathers in one place it is known as static electricity the word static means something that does not move ; electricity that moves from one place to another is called current electricity.

Conductors and Insulators - Super Teacher Worksheets Conductors and Insulators A conductor is a material that allows electricity to flow through it. Grade 6 Science: Electricity created by areynolds.

Electric Vocabulary s that scientists began to learn more about the nature of electricity, and one of the pioneers of the field was Benjamin Franklin, who was an intrepid investigator. Electricity Worksheets - drzn36sxxg.Do you have questions? Determine the force on the charge. The distance between the charges is 0. What are the magnitude and direction of the E-field at the midpoint of the dipole? Assume the positive charge is on the left. Also determine the force magnitude and direction for an electron at that position in the field.

The E-field from both charges will point to the right, thus the overall E-field is to the right. They are both positive, but the second charge has twice the magnitude of the first. Determine the overall direction of the E-field at the various positions listed below: A. At the origin B. This position is equidistant to both charges. Since q 2 is larger, it produces a bigger E-field.

The superposition of the fields shows an overall E-field along the —x axis. Choice 3. Charge q 1 produces an E-field pointing into the 4 th quadrant while charge q 2 produces an E-filed pointing into the 3 rd quadrant.

The superposition of the fields shows an overall E-field in the 3 rd quadrant. Choice 7. Depending upon the value of the y coordinate, the superpositioned E-field can be in any direction between 91 and degrees. Choice 6. Since q 2 is larger and closer, it produces a bigger E-field. Thus the overall E-field is in that direction. Choice 1. Depending upon the value of the y coordinate, the superpositioned E-field can be in any direction between 1 and 89 degrees.

Choice 5. Charge q 1 produces an E-field pointing into the 4 th quadrant while charge q 2 produces an E-field pointing into the 1 st quadrant. The superposition of the fields shows an overall E-field along the -x axis. Charge q 2 same charge as q 1 is located at the origin. Assume that these charges are unable to move. As it moves, the force and the acceleration will decrease.

Thus, it will continue to speed up, but at a lower rate at time goes on. Determine the magnitude of the force and then describe the trajectory each particle will undergo, including their velocities and accelerations. The instantaneous force magnitude they both exert on each other is determined by Coulomb's Law.

They will both speed up as time goes on, but the smaller particle will speed up faster because, with a lower mass, it will have a greater acceleration due to the common force. As they move apart the accelerations on each will decrease because the force will decrease. At some point the accelerations will be so small as to approach zero, and the particles will essentially stop speeding up and simply move away from each other at a constant speed.Life without electricity is unimaginable.

Snip the pictures, sort them and glue them in the correct columns. Answer the following.The actual answers will be shown in brackets, followed by an explanation. If the object is charged negative, it will repel electrons from the knob into the vanes. The vanes will both become negatively charged and repel each other. If the object is charged positive it will draw electrons up from the vanes into the knob.

The vanes will both become positively charged and repel each other. The proton and electron have equal but opposite charges, so the forces that they experience will be equal and opposite as well. Then solve:. The spheres are metal, so the electrons are free to spread out. The spheres are identical, so they will be evenly distributed over the surface of both spheres, resulting in the same number of excess electrons on each sphere. If the distance between the objects was increased from 1.

The only way to get the coulombs to cross out is to multiply our givens together. Of course, it is always better to look up the formula, if you have the opportunity.

The question asks only for the magnitude of the force, so that is why we leave the negative sign off our final answer. Lesson 5—1 Review 1. Lesson 5—2 Review 1. Lesson 5—3 Review 1.
