Two identical balls are projected, one vertically up and the other at an angle of `30^(@)` to the horizontal, with same initial speed. The potential energy at the highest point is in the ratio:

A

`1:1`

B

`2:1`

C

`3:2`

D

`4:1`

Text Solution

Verified by Experts

The correct Answer is:
D

`h_A=(u^2)/(2g)`,`h_B=(u^2sin^(2)30^@)/(2g)=(u^2)/(8g)`
`(U_A)/(U_B)=(mgh_A)/(mgh_B)=(4)/(1)`
