3. Which of the following statements is/are true?

a) The electric field is zero at the midpoint between two negative charges of equal magnitude.
b) The electric field is zero at the midpoint between a positive and a negative charge of equal magnitude.
c) The electric potential is zero at the midpoint between a positive and a negative charge of equal magnitude.

Prelab 3:

1. Read the lab thoroughly.

2. Describe in your own words what "potential energy" means in physics, and then tell us what you think "electrical potential energy" means, specifically.

3. Please describe the electric field near a large plane of charge.

4. What is the principle of superposition? (Describe briefly and in your own words what this principle means for electric fields, and what it means for electric potentials.

We thank you for taking the time to fill out this prelab.
