A) \[{{45}^{o}}\]
B) \[{{90}^{o}}\]
C) \[{{60}^{o}}\]
D) \[{{30}^{o}}\]
Correct Answer: B
Solution :
When bigger pendulum of time period\[(5T/4)\] completes one vibration, the smaller pendulum will complete \[(5/4)\] vibration. It means the smaller pendulum will be leading the bigger pendulum by phase\[\frac{T}{4}s=\frac{\pi }{2}rad={{90}^{o}}\].You need to login to perform this action.
