Concepts Of Physics MCQ Edition [Volume 1]PhysicsSimple Harmonic Motion
Which of the following will experience a change in their time period when transported to the moon?
Options
- AA simple pendulum
- BA physical pendulum
- CA torsional pendulum
- DA spring-mass system
Correct answer
B. A physical pendulum
Step-by-step solution
The time period of a simple pendulum is given by T = 2 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 I mgd . This also depends on g , so its time period will change. The time period of a torsional pendulum is T = 2 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 m k , where k is the sp
