Question

A Bob of a second pendulum is replaced by another Bob of double mass.the new time period will be?? ​

Answer 1

Answer:

The time period will be unchanged. It will be the same as the first pendulum.

Explanation:

The time period of a pendulum (T) only depends on two factors,

1. Length of string holding the bob in the pendulum (L) , &
2. Acceleration due to gravity (g)

The relation is : T = 2π √L/g

Therefore, doubling the mass on the bob on the second pendulum will not affect the time period of the pendulum.
