A stone dropped from a building of height `h` and it reaches after `t` second on the earth. From the same building if two stones are thrown (one upwards and other downwards) with the same speed and they reach the earth surface after `t_(1)` and `t_(2)` seconds, respectively, then

A

`t = t_1 - t_2`

B

`t = (t_1 + t_2)/(2)`

C

`t = sqrt(t_1t_2)`

D

`t = t_1^2 t_2^2`

Text Solution

Verified by Experts

The correct Answer is:
C
