Two bodies A (of mass 1 kg) and B (of ma...

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)/(2)`

B

`(12)/(5)`

C

`(5)/(12)`

D

`(4)/(5)`

Text Solution

Verified by Experts

The correct Answer is:
D
`(t_(1))/(t_(2))=sqrt((2h_(1))/(g))/sqrt((2h_(2))/(g))=sqrt(h_(1))/sqrt(h_(2))=sqrt(16)/(sqrt(25))=(4)/(5)`
