A body is allowed to fall from a height ...

A body is allowed to fall from a height of `100 m`. If the time taken for the first `50 m` is `t_1` and for the remaining `50 m` is `t_2` then :

A

` 5 :2 `

B

` 3: 1 `

C

` 3: 2`

D

` 5 : 3`

Text Solution

Verified by Experts

The correct Answer is:
A
` t_1 :t_2 =(10)/(sqrtg) xx ( sqrtg)/(10 (sqrt 2-1)) =(1)/(0.4) =(10)/(4) =(5)/(2)`
