MHT CET 2024 Physics question
A particle of mass 'm' is performing uniform circular motion along a circular path of radius 'r'. its angular momentum about the axis passing through the centre and perpendicular to the plane is 'L'. The kinetic energy of the particle is
Answer: (A)
Solution
For circular motion the velocity is perpendicular to the radius, so the angular momentum is , giving . Kinetic energy
