A body slides down a fixed curved track ...

A body slides down a fixed curved track that is one quadrant of a circle of radius `R`, as in the figure. If there is no friction and the body starts from rest, its speed at the bottom of the track is

5gR

`sqrt5gR`

`sqrt2gR`

`sqrtgR`

Text Solution

Verified by Experts

The correct Answer is:

`(3)`
