Two simple pendulum of length l and 16l are released from the same phase together. They will be at the same time phase after a minimum time.

Two simple pendulums of length 5 m and 20 m are given small displacements in the same direction at the same time. The minimum number of oscillations, the shorter pendulum has completed, when the phase difference between them become zero again, is

Two simple pendulums of length 1m and 16m respectively are both given small displacements in the same direction at the same instant. After how many oscillations of the shorter pendulum will, the two pendulums vibrate in the same phase ?

Two simple pendulums of length 1m and 1.21 m are started oscillating from some position. Find the minimum time (in second) after which they again start from same position.

Two simple pendulums of length 100 m and 121 m start swinging together in the same directionvith same phase.They will swing together again in same phase after.

Two simple pendulum of length 1m and 16m respectively are both given small displacement in the same direction of the same instant. They will be phase after one shorter pendulum has complated a oscillations. The value of n is
