Two balls are projected simultaneously with the same velocity u from the top of a tower, one vertically upwards and the other vertically downwards. Their respective times of the journeys are `t_(1)` and `t_(2)` At the time of reaching the ground, the ratio of their final velocities is

A

`1 : 1`

B

`1 : 2`

C

`2 : 3`

D

`2 : 1`

Text Solution

Verified by Experts

The correct Answer is:
