Angular momentum of a single particle moving with constant speed along circular path :

Options

  1. Aremains same in magnitude but changes in the direction
  2. Bremains same in magnitude and direction
  3. Cis zero
  4. Dchanges in magnitude but remains same in the direction

Correct answer

B. remains same in magnitude and direction

Step-by-step solution

The angular momentum is defined as the vector product of linear momentum and perpendicular distance, L → = r → × p → = r → × m v → , And direction will be upward & remain constant.
