The ratio of frequencies of two oscillating pendulums are 3: 2 . Their lengths are in the ratio

Options

  1. A2 : 3
  2. B9: 4
  3. C3 : 2
  4. D4: 9

Correct answer

D. 4: 9

Step-by-step solution

The frequency of oscillation is given by: n = 1 2 g L So, Frequency n 1 L n ₁ n ₂ = L ₂ ~L ₁ L ₁ ~L ₂ = n ₂^2 n ₁^2 = 4 9
