Question

Kaushik had three pendulum bobs made of steel of the same length but different masses of 10 g, 50 g and 100 g respectively. When he performed an experiment with them to find the time period, which of these statements would he consider to be correct? a. The time period is maximum with 10 g bob. b. The time period is maximum with 50 g bob. c. Time period remains the same in all. d. None of these is true.

Answer 1

Answer:

Time period remains the same.

Explanation:

Time period is defined as

T =

$2\pi \sqrt{ \frac{l}{g} }$

Hence, time period of a pendulum is independent of the mass of the bob.
