Two bodies `A` (of mass `1 kg`) and `B` (of mass `3 kg`) are dropped from heights of `16 m` and `25 m`. Respectively. The ratio of the time taken to reach the ground is :
(a) `5/4` (b) `12/5` (c) `5/12` (d) `4/5`

A

`5/4`

B

`12/5`

C

`5/12`

D

`4/5`

Text Solution

Verified by Experts

The correct Answer is:
D
`therefore h=(1)/(2)"gt"^(2)therefore(t_(1))/(t_(2))=sqrt((h_(1))/(h_(2)))=sqrt((16)/(25))=(4)/(5)`
