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
- A2 3
- B3 2
- C4 3
- 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
