Two simple pendulums of lengths 0.5m and 2.0m respectively are given small linear displacement in one direction at the same time. They will again be in phase when the pendulum of shorter length has completed…………..oscillations.

Text Solution

Verified by Experts

The correct Answer is:

The time period of the shorter pendulum is half that of the longer pendulum. Therefore, the pendulums will again be in phase (at the mean position). When the shorter pendulum has completed 2 oscillations.
