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

To complete loop, velocity at lowerst point
`v ge sqrt(5 g R)`
`v_(m i n) = sqrt(5 g R)`
