In a diagram of charges and electric field lines charge Q1has twelve field lines going outward from it and charge Q2has three field lines going into it. If one of the charges is 100 nC, what is the other one?
 a. 25 nC
  b. 100 nC
  c. 25 nC
  d. 100 nC
  e. Both answers b and c can be correct.

Question 2

Suppose a uniform electric field of 4 N/C is in the positive x direction. When a charge is placed at and fixed to the origin, the resulting electric field on the x axis at x = 2 m becomes zero. What is the magnitude of the electric field at x = 4 m on the x axis at this time?
 a. 0
  b. 1 N/C
  c. 2 N/C
  d. 4 N/C
  e. More information is needed to find the resulting field magnitude at this position.
