0A particle of mass \( \mathrm{m} \) is rotating in a plane in a circular path of radius \( r \). Its angular momentum is \( \mathrm{L} \). The centripetal force acting on the particle is
(1) \( \frac{\mathrm{L}^{2}}{\mathrm{mr}} \)
(2) \( \frac{\mathrm{L}^{2} \mathrm{~m}}{\mathrm{r}} \)
(3) \( \frac{\mathrm{L}^{2}}{\mathrm{mr}^{2}} \)
(4) \( \frac{\mathrm{L}^{2}}{\mathrm{mr}^{3}} \)
