Question

A point charge +Q is fixed on a very large horizontal frictionless tabletop. A second point charge +q is released from rest near the stationary charge and is free to move. Which statement best describes the motion of +q after it is released?

A point charge +Q is fixed on a very large horizontal frictionless tabletop. A second point charge +q is released from rest near the stationary charge and is free to move. Which statement best describes the motion of +q after it is released?

Its speed will be greatest just after it is released. As it moves farther and farther from +Q, its speed will decrease. Its acceleration is zero just after it is released. As it moves farther and farther from +Q, its speed will keep increasing. As it moves farther and farther from +Q, its acceleration will keep increasing.

Explanation / Answer

As it moves farther and farther from +Q, its speed will decrease.
