A body is rotating about its own axis. Its rotational kinetic energy is ' x ' and its angular momentum is ' y '. Hence its moment of inertia about its own axis is

Options

  1. Ax 2y
  2. By 2x
  3. Cx^2 2y
  4. Dy^2 2x

Correct answer

D. y^2 2x

Step-by-step solution

Rotational kinetic energy is given by K = L^2 2I Substituting the given values, K = x and L = y x = y^2 2I I = y^2 2x Answer: y^2 2x
