An object is moving in a circle at constant speed v . The magnitude of the rate of change of momentum of the object is

Options

  1. Azero
  2. Bproportional to v^2
  3. Cproportional to v^3
  4. Dproportional to V

Correct answer

B. proportional to v^2

Step-by-step solution

Rate of change of momentum of the object, p t =F_ ext = m v^2 r p t v^2 (where, m and r are constant)
