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

Question 2

Two particles, each having a mass of 3.0 g and having equal but opposite charges of magnitude 5.0 nC, are released simultaneously from rest when the two are 5.0 cm apart. What is the speed of either particle at the instant when the two are separated by 2.0 cm?
 a. 2.1 m/s
  b. 1.5 m/s
  c. 1.8 m/s
  d. 2.4 m/s
