A particle is moving in a circle of radius R with constant speed v, if radius is double then its centripetal force to keep the same speed should be

A

Doubled

B

Halved

C

Quadrupled

D

Unchanged

Text Solution

Verified by Experts

The correct Answer is:
B
`F = (mv^(2))/r`, For same mass and speed if radius is doubled then force should be halved `rArr F prop 1/r`
