Correct answer: B. A physical pendulum

The time period of a simple pendulum is given by

T = 2\pi \sqrt{\dfrac{l}{g}}

. Since the acceleration due to gravity

g

on the moon is different from that on Earth, its time period will change.

The time period of a physical pendulum is given by

T = 2\pi \sqrt{\dfrac{I}{mgd}}

. This also depends on

g

, so its time period will change.

The time period of a torsional pendulum is

T = 2\pi \sqrt{\dfrac{I}{C}}

, where

C

is the torsional constant. It is independent of

g

, so its time period will not change.

The time period of a spring-mass system is

T = 2\pi \sqrt{\dfrac{m}{k}}

, where

k

is the spring constant. It is independent of

g

, so its time period will not change.

Thus, only the simple pendulum and the physical pendulum will experience a change in their time periods.
