Question

Two pendula have time periods T and $\frac{5T}{4}$. They start SHM at the same time from the mean position. The phase difference between them after the pendulum with larger period completes one oscillation is

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Since $\frac{5T}{4}=T+\frac{T}{4}$, the phase difference is $\frac{\pi }{2}$.
