Correct Answer: D
Solution :
[d] Before the second ball is dropped, the first ball would have travelled some distance say \[{{s}_{0}}=\frac{1}{2}g{{t}_{0}}^{2}\], after dropping the second ball, the relative acceleration of both balls becomes zero. So distance between then increase linearly. After some time, the first ball will collide with the ground and the distance between them will start decreasing and the magnitude of relative velocity will be increasing for this time. Option (4) represents all these clearly.You need to login to perform this action.
