Four types of oscillatory systems ; a simple pendulum ; a physical pendulum ; a torisional pendulum and a spring-mass system, each of same time period are taken to the Moon. If time periods are measured on the moon, which system or systems will have it unchanged :
A
Only spring-mass system.
B
Spring-mass system and torisional pendulum.
C
Spring-mass system and physical pendulum
D
None
Answer
Spring-mass system and torisional pendulum.
Explanation
Solution
