Suppose in the absence of air resistance,`R=OB,H+AC,t_(1)=t_(OA)` and `t_(2)=t_(AB)`.If air resistance is taken into consideration and the corresponding values are `R',H',T_(1)'` and `t_(2)` then

A

`R'ltR,H'ltH,t_(1)'gtt_(1)` and `t_(2)'gtt_(2)`

B

`R'ltR,H'ltH,t_(1)'gtt_(1)` and `t_(2)'ltt_(2)`

C

`R'ltR,H'gtH,t_(1)'gtt_(1)` and `t_(2)'ltt_(2)`

D

`R'ltR,H'ltH,t_(1)'ltt_(1)` and `t_(2)'gtt_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
During upward journey gravity and air fraction both will oppose the motion. Hence, `t_(1)' lt t_(1)`
