In an imaginary atmosphere, the air exerts a small force F on any particle in the direction of the particle's motion. A particle of mass m projected upward takes time `t_1` and reaching the maximum height and `t_2` in the return journey to the original point. Then

A

`t_(1) lt t_(2)`

B

`t_(1) gt t_(2)`

C

`t_(1) = t_(2)`

D

The relation between `t_(1)` and `t_(2)` depends on the mass of the particle
