Question

draw a graph representing the variation of square of time period t square with the length L of a pendulum​

Answer 1

The simple pendulum exhibits Simple Harmonic Motion (SHM) as the acceleration of the pendulum bob is directly proportional to the displacement from the mean position and is always directed towards it. The time period (T) of a simple pendulum for oscillations of small amplitude, is given by the relation

T=2πL/G‾‾‾‾√

Where L is the length of the pendulum and g is the acceleration of gravity
