Three point charges are positioned on the x axis. If the charges and corresponding positions are +32 mC at x = 0, +20 mC at x = 40 cm, and -60 mC at x = 60 cm, what is the magnitude of the electrostatic force on the +32-mC charge?
 a. 84 N
  b. 12 N
  c. 36 N
  d. 50 N
  e. 48 N

Question 2

 a. 13 N
  b. 77 N
  c. 39 N
  d. 25 N
  e. 45 N
