A simple pendulum executing $S.H.M.$ is falling freely along with the support. Then
Its periodic time decreases
Its periodic time increases
It does not oscillate at all
None of these
A man having a wrist watch and a pendulum clock rises on a $TV$ tower. The wrist watch and pendulum clock per chance fall from the top of the tower. Then
The angular amplitude of a simple pendulum is $\theta_0$. The maximum tension in its string will be
For a simple pendulum the graph between $L$ and $T$ will be.
The ratio of frequencies of two pendulums are $2 : 3$, then their length are in ratio
Can simple pendulum clock be used in an artificial satellite ? Why ?
