A ball of mass m performs uniform circular motion in a circle of radius R. Linear momentum is represented by p. The radial force acting on the particle is

A

`mRp^(2)`

B

`(mp^(2))/R`

C

`p^(2)/(mR)`

D

`(p^(2)R)/m`

Text Solution

Verified by Experts

The correct Answer is:
C
Momentum, p=mv, and Radical force `=(mv^(2))/R`
As we know that, `v = p/m, therefore F = m/R (p/m)^(2) =(mp^(2))/(m^(2)R) =p^(2)/(mR)`
