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)m//r`
C. `L^(2)//m^(2)r^(2)`
D. `L^(2)//mr^(3)`

Explanation

`L=mvrimpliesv=(L)/(mr)`
`F=(mv^(2))/(r )=(m)/(r )((L)/(mr))^(2)=(L^(2))/(mr^(3))`
