A particle of mass `m` is moving in a plane along a circular path of radius `r`. Its angular momentum about the axis of rotation is `L`. The centripetal force acting on the particle is.

Options

A. `(L^(2))/(mr)`
B. `(L^(2))/(mr^(2))`
C. `(L^(2))/(mr^(3))`
D. `(L)/(mr^(2))`

Answer

C

Explanation

`L=mvr thereforev=(L)/(mr)`
`F=(mv^(2))/(r)=(L^(2))/(mr^(3))`
