A particle of mass ' m ' is rotating along a circular path of radius ' r ' having angular momentum ' L '. The centripetal force acting on the particle is given by

Options

  1. AL ^2 mr
  2. BL ^2 mr ^2
  3. CmL ^2 r
  4. DL ^2 mr ^3

Correct answer

D. L ^2 mr ^3

Step-by-step solution

array ll & Centripetal force =m ^2 r & = L I = L m r^2 ( L=I ) & F=m ( L m r^2 )^2 r= m^2 r m^2 r^4 = L^2 m r^3 array
