Avg difficulty 2.5

In an experiment, three microscopic latex spheres are sprayed into a chamber and become charged with +3e, +5e, and −3e, respectively. Later, all three spheres collide simultaneously and then separate. Which of the following are possible values for the final charges on the spheres? Select two answers.

  1. +4e, −4e, +5e
  2. −4e, +4.5e, +4.5e
