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
- A3 T
- B3 / 2 T
- C4 T
- 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
