Two identical particles, each with a mass of 4.5 g and a charge of 30 nC, are moving directly toward each other with equal speeds of 4.0 m/s at an instant when the distance separating the two is equal to 25 cm. How far apart will they be when closest to one another?
 a. 9.8 cm
  b. 12 cm
  c. 7.8 cm
  d. 15 cm
  e. 20 cm

 a. 2.1 m/s
  b. 1.5 m/s
