In a circus , stuntman rides a motor bike in a circular track of radius R in the vertical plane. The minimum speed at highest point of track will be _______ .

A

`sqrt(2gR)`

B

2 gR

C

`sqrt(3gR)`

D

`sqrt(gR)`

Text Solution

Verified by Experts

The correct Answer is:
D

At highest point
`mg +N = (mv^(2))/( R)`
For `V_("min") N = 0 implies V_("min") = sqrt(gR)`
