The answer is NOT C Two positive point charges are released

The answer is NOT C.

Two positive point charges are released on a frictionless surface. Which of the following best describes their subsequent motion? Select One of the Following: The particles remain stationary. The particles move apart with constant velocity. The particles move apart with a velocity that decreases with time. The particles move apart with a velocity that increases with time. The particles move apart with a velocity that increases for a while and then becomes constant. Selected Answer: Answer (c) Answer (a) Answer (b) Answer (c) Answer (d) Answer (e)

Solution

each particle experinces a force that diminishes over distance. But you need to understand that the force is always along direction of velocity so it will always accelerate.

So the answer is D
