Solution

## The correct option is C Both the balls will hit the ground with the same velocityBall A will return to the top of tower after T=2ug=2×1010=2 s with a speed of 10 ms−1 downward. And at the same moment B is also projected downward with 10 ms−1. So both reach ground simultaneously. Also they will hit the ground with same speed.
