Question

Two simple pendulums are drawn to same side from their mean position and are released simultaneously. Their time periods are 2 s and 3s. The phase difference between the pendulums when the longer pendulum completes one oscillation is
A. `(pi)/(2)` rad
B. `(pi)/(2)` rad
C. `(2pi)/(3)` rad
D. `pi` rad

Answer 1

Correct Answer - D
`Deltaphi=omega_(1)t-omega_(2)t=((2pi)/(2)-(2pi)/(3))xx3`
`=2pi((1)/(6))xx3=pi` radian.
