I start with a pair of positive charges a set distance apart at rest. Then, I let go.  Which of the following describes the subsequent behavior of the system? A   The charges move toward each other. Their speed increases until they collide. B   The charges move apart. The speed keeps increasing through time.  C   The motion is unpredictable.

The speed increases at first, but falls to zero as tehy get very far apart.
