To show that a simple pendulum executes simple harmonic motion, it is necessary to assume that
Length of the pendulum is small
Mass of the pendulum is small
Amplitude of oscillation is small
Acceleration due to gravity is small
The length of a seconds pendulum is .... $cm$
A simple pendulum is suspended from the roof of a trolley which moves in a horizontal direction with an acceleration $a$, then the time period is given by $T = 2\pi \sqrt {\frac{l}{{g'}}} $, where $g'$ is equal to
