A positive pointt charge Q is fixed on a very large horizont

A positive pointt charge Q is fixed on a very large horizontal frictionless tabictop. A second positive pointt charge q is released from rest near the stationary charge and is free to move. Which statement best describe the rection of q after it is released? A) Its speed will be greatest just after is is released. B) Its acceleration is once just after it is released. C) as it moves farther and farther from Q. its acceleration will keep increasing. D) As it moves farther and farther from Q, its speed will decrease. E) As it moves farther and farther from Q, its speed will keep increasing. 6) One very small uniformly charged plastic ball is located directly above another such charge in a lost tube as shown in the figure. The balls are in equilibrium a distance d apart. If the charge on each ball is doubled, the distance between the balls in the best tub e would become
