If the time period is doubled, then the angular momentum of the body will (provided the moment of inertia of the body is constant)

Options

  1. Aremain constant
  2. Bquadruple
  3. Cbecome half
  4. Ddouble

Correct answer

C. become half

Step-by-step solution

As we know. L = I ω ⇒ L = I × 2 π T L ∝ 1 T Given, T 2 = 2 T Hence L 1 L 2 = 2 T T ⇒   L 2 = L 1 2
