Pendulum Of Large Length But Small Amplitudes

The periodic time of a simple pendulum of length 1 m and amplitude 2 cm is 5 seconds. If the amplitude is made 4 cm , its periodic time in seconds will be

A simple pendulum oscillating with a small amplitude has a time period of T = 1.0s . A horizontal thin rod is now placed beneath the point of suspension at a distance equal to half the length of the pendulum. The string collides with the rod once in each oscillation and there is no loss of energy in such collisions. Find the new time period T of the pendulum

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.

The motion of a simple pendulum when it oscillates with small amplitude is

Which of the following statements is not true ? In the case of a simple pendulum for small amplitudes the period of oscillation is
