As the temperature is increased, the time period of a pendulum

A

increases as its effective length increases even though its centre of mass still remains at the centre of the bob.

B

decreases as its effective length increases even though its centre of mass still remains at the centre of the bob.

C

increases as its effective length increases due to shifting of centre of mass below the centre of mass below the centre of the bob.

D

decreases as its effective length remains same but the centre of mass shifts above the centre of the bob.

Text Solution

Verified by Experts

The correct Answer is:
A
As temperature increases, length of pendulum increases.
Time period of pendulum `T=2pisqrt(L/g)" "(2pi" and g are constant")`
`:.propsqrt(L)`
`:.` T increases with increases in L.
