Time period of a simple pendulum of length ' L ' is T₁ . Time period of a uniform rod of same length ' L ' suspended from one end and oscillating in a vertical plane is T₂ . Amplitude of oscillation is small in both the cases. Then T₁ T₂ is

Options

  1. A2 3
  2. B3 2
  3. C4 3
  4. D1

Correct answer

B. 3 2

Step-by-step solution

Length of pendulum =L Time period of simple pendulum T₁=2 L g Length of rod =L Time period of rod; aligned & T₂=2 2 L 3 g [ T=2 I m g r_ c m and r_ c m = / 2 ] & T₁ T₂ = 2 L / g 2 2 L / 3 g = 3 2 aligned
