Two simple pendulum of length `5m` and `20m` respectively are given small displacement in time direction at the same time. They will again in the plane when the pendulum of starter length has complated oscilation.

Two simple pendulums of length 0.5 m and 20 m respectively are given small linear displacement in one direction at the same time. They will again be in the phase when the pendulum of shorter length has completed oscillations [ nT_(1)=(n-1)T_(2) , where T_(1) is time period of shorter length & T_(2) be time period of longer length and n are no. of oscillations completed]

Two simple pendulums of length 0.5 m and 20 m, respectively are given small linear displacement in one direction at the same time. They will again be in the phase when the pendulum of shorter length has completed oscillations.

Two simple pendulums of length 0.5 m and 20 m, respectively are given small linear displacement in one direction at the same time. They will again be in the phase when the pendulum of shorter length has completed oscillations.

Two simple pendulums of length 0.5 m and 20 m, respectively are given small linear displacement in one direction at the same time. They will again be in the phase when the pendulum of shorter length has completed oscillations.

Two simple pendulums of length 5 m and 20 m 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 completedthe number of oscillations are
