A particle of mass m is circulating on a circle of radius r having angular momentum L then the centripetal force will be

Options

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

Answer

c

Explanation

`[L=mvr rArr v = (L)/(mr) , F_(c) = (mv^(2))/(r) = (m)/(r) ((L^(2))/(m^(2)r^(2)))]`
