Small bob of a simple pendulum has mass $m$ and the length of the pendulum is $l$. It is oscillating on a circular arc of angle $\theta$ in a vertical plane. At the end of this arc another ball of mass $m$ is placed at rest. Momentum transferred to this ball by the bob of the pendulum is

Two simple pendulums of length $1 \mathrm{m}$ and $1.21 \mathrm{m}$ are their mean position with their velocities in the same direction at some instant. After how many oscillations of bigger pendulum they will again be in same phase?

At some instant the bob of the simple pendulum is at the mean position. The time after which its kinetic and potential energies will be equal is

Time period of a simple pendulum is $T$. Time taken by it to complete $\frac{3}{8}$ oscillations starting from mean position is

Time period of oscillation of simple pendulum of length $L$ hanging from the ceiling of a vehicle which moves down an inclined plane without friction, having inclination $60°$ is equal to

The angular amplitude of a simple pendulum is ${\theta }_0$. The maximum tension in its string will be
