What is the minimum velocity with which a body of mass m must enter a vertical loop of radius R so that it can complete the loop?

A

`sqrt(5 gR)`

B

`sqrt(gR)`

C

`sqrt(2 gR)`

D

`sqrt(3 gR)`

Text Solution

Verified by Experts

The correct Answer is:
A
When minimum speed of body is `sqrt(5gR)`, then no matteer from where it enters the loop, it will complete full vertical loop.
