The ratio of frequencies of oscillations of two simple pendulums is 3: 4 , then their lengths are in the ratio

Options

  1. A16: 9
  2. B9:16
  3. C3 : 4
  4. D4 : 3

Correct answer

A. 16: 9

Step-by-step solution

Frequency of simple pendulum is given by aligned f &= 1 2 g f ₁ f ₂ = ₂ ₁ 3 4 &= ₂ ₁ or 9 16 = ₂ ₁ ₁ ₂ &= 16 9 aligned
