If the particle is projected down onto the inclined plane at same speed and angle with the inclined plane the ratio of the time of flight and time of flight for upward projection is :

A

`1:sqrt(2)`

B

`sqrt(2):1`

C

`1:1`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
Time of flight will be same in both cases, because `u_(y)` is same in both cases.
