A person standing oin the floor of an elevator drops as coin. The coin reaches the floor of the elevator in a time `t_1` if the elevator is stationary and in the `t_2` if it is moving uniformly. Then

A

`t_(1)=t_(2)`

B

`t_(1)ltt_(2)`

C

`t_(1)gtt_(2)`

D

`t_(1)ltt_(2)` or `t_(1)ltt_(2)` depending on whether the lift is going up or down

Text Solution
