A body slides down a smooth inclined plane of height `h` and angle of inclination `30^(@)` reaching the bottom with a velocity `v`.Without changing the height, if the angle of inclination is doubled, the velocity with which it reaches the bottom of the plane is

A

`v`

B

`v//2`

C

`2v`

D

`sqrt2 v`

Text Solution

Verified by Experts

The correct Answer is:
A
`V=sqrt(2gh)` and `V` does not depends on `theta` when `h="constant"`
