The power (P) is supplied to rotating body having moment of inertia 'I' and angular acceleration ' '. Its instantaneous angular velocity is

Options

  1. AI P
  2. BPI
  3. CP I
  4. DP I

Correct answer

D. P I

Step-by-step solution

Power P supplied to a rotating body is given by the product of torque and angular velocity . P = The torque acting on the body is related to its moment of inertia I and angular acceleration by the relation: = I Substituting the value of in the power equation: P = (I ) Rearranging for instantaneous angular velocity : = P I Answer: P I
