If the angular momentum of a particle of mass $m$ rotating along a circular path of radius $r$ with uniform speed is L, the centripetal force acting on the particle is
Show Hint
This formula is very common in planetary motion and atomic physics (Bohr's model). Memorizing the relationship $F_c = \frac{L^2}{mr^3}$ can save valuable time in entrance exams!
