Identical 8.0-mC point charges are positioned on the x axis at x = 1.0 m and released from rest simultaneously. What is the kinetic energy of either of the charges after it has moved 2.0 m?
 a. 84 mJ
  b. 54 mJ
  c. 96 mJ
  d. 63 mJ
  e. 48 mJ

Question 2

 a. -2.2 mC
  b. +6.7 mC
  c. -2.7 mC
  d. +8.0 mC
  e. -1.1 mC
