A point charge Q is placed on the x axis at the origin. An identical point charge is placed on the x axis at x = -1.0 m and another at x = +1.0 m. If Q = 40 mC, what is the magnitude of the electrostatic force on the charge at x = +1.0 m?
 a. 29 N
  b. 14 N
  c. 11 N
  d. 18 N
  e. 7.0 N

Question 2

 a. 16 N
  b. 27 N
  c. 32 N
  d. 11 N
  e. 3.0 N
