Time taken by an object falling from rest to cover the height of `h_(1)` and `h_(2)` is respectively `t_(1)` and `t_(2)` then the ratio of `t_(1)` to `t_(2)` is

A

`h_1 : h_2`

B

`sqrth_1 : sqrth_2`

C

`h_1: 2h_2`

D

`2h_1 :h_2`

Text Solution

Verified by Experts

The correct Answer is:
B
`t = sqrt((2h)/(g) rArr t prop sqrth `
`t_1/t_2 = sqrt(h_1/h_2)`
