Two particles, each having a mass of 3.0 mg and having equal but opposite charges of magnitude of 6.0 nC, are released simultaneously from rest when they are a very large distance apart. What distance separates the two at the instant when each has a speed of 5.0 m/s?
 a. 4.3 mm
  b. 8.6 mm
  c. 7.3 mm
  d. 5.6 mm
  e. 2.2 mm
