A positive charge Q is fixed on a very large horizontal frictionless tabletop. A second positive 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) As it moves farther and farther from Q, its acceleration will keep increasing.
(b) As it moves farther and farther from Q, its speed will decrease.
(c) Its speed will be greatest just after it is released.
(d) Its acceleration is zero just after it is released.
(e) As it moves farther and farther from Q, its speed will keep increasing.
