If the length of a pendulum is made 9 times and mass of the bob is made 4 times, then the value of time period becomes :

Options

  1. A3 T
  2. B3 / 2 T
  3. C4 T
  4. D2 T

Correct answer

A. 3 T

Step-by-step solution

Time period T=2 l g i.e., time period does not depend on the mass of the bob. aligned & & T & l & & T₁ T₂ & = l₁ l₂ & & T T₂ & = l 9 l & & T₂ & =3 T aligned
