A particle of mass m is rotating in a plane in circularpath of radius r . Its angular momentum is L . The centripetal force acting on the particle is

Options

  1. AL² m r
  2. BL² m r
  3. CL² m² r²
  4. DL² m r³

Correct answer

D. L² m r³

Step-by-step solution

Centripetal force, F= m v² r = m r L² m² r² = L² m r³ [ . As .L=m v r v= L m r ]
