Answer the Reading Questions below. Please answer each question.

1. An object has a charge of 1 C. What does that tell us about the total number of protons in the object? Explain your answer.

2. Two objects are attracted to each other through electrostatic attraction. What do you know about the two objects?

Both objects are charged and they have opposite charges.
Both objects are charged and they have the same type of charge.
At least one of the objects is charged.

3. An object that is initially electrically neutral is charged by induction. Can you tell if the object is an insulator or conductor? Explain.

4. Under what circumstances can you use Coulomb's law?

5. An obect with charge Q1 is positioned at (x,y) = (0,0). Another object with charge Q2 is located at (2,2). Is the x component of the force on the second obejct from the first equal to kQ1Q2/4? Why or why not?

6. How is the electric field related to the electric force?

7. If you know the electric field at a certain location in space, how do you determine the magnitude and direction of the force on a charged particle at that location in space?

8. What does the density of electric field lines represent?

9. What do the arrows drawn on electric field lines represent?

10. Is it possible for an electric dipole to feel a net force, but no torque in an electric field? Explain your answer.

11. How does the symmetry of a situation help determine the electric field of a continuous distribution of charge?
