A ball is thrown vertically upwards from the ground. If `T_1` and `T_2` are the respective time taken in going up and coming down, and the air resistance is not ignored, then

Options

A. `t_(1) gt t_(2)`
B. `t_(1) = t_(2)`
C. `t_(1) lt t_(2)`
D. `t_(1)` can be greater or smaller depending upon the initial velocity of the body

Answer

C

Explanation

In upward motion, resistance of air acts downward while in downward motion it acts upwards, always opposite to velocity.
