Question

What is the effect on the time period of a simple pendulum, if the mass of the bob is doubled? (A) Halved (B) Doubled (C) Becomes eight times (D) Becomes zero

Tardigrade Admin · Accepted Answer

The time period of a simple pendulum is T=2π √(l/g) where l is length of suspension of pendulum, g is acceleration due to gravity. From the above expression, it is clear that time period of a simple pendulum is not dependent on the mass of bob, hence no effect.

Halved

Doubled

Becomes eight times

Becomes zero

The time period of a simple pendulum is $T = 2 π \frac{l}{g}$ where $l$ is length of suspension of pendulum, g is acceleration due to gravity. From the above expression, it is clear that time period of a simple pendulum is not dependent on the mass of bob, hence no effect.
