Q(a). Two simple pendulums A and B of different lengths are suspended from the same string as shown in the figure. When A is displaced from its mean position and is let go, it is found that B also starts vibrating.
1. Name the phenomenon that is responsible for the vibrations of B.
ii. Does the frequency of the vibration of B depend on its own length or one the frequency of the vibration of A ?
iii. What would happen to the amplitude of the vibration of B if its string length was made equal to the string length of A?
iv. Name the phenomenon which occurs when the string length of B is made equal to the string length of A.
