The length of a seconds pendulum at a height $h=2 R$ from earth surface will be.(Given: $R =$ Radius of earth and acceleration due to gravity at the surface of earth $g =\pi^{2}\,m / s ^{-2}$ )
If pendulum is released from given position find velocity of Bob when it reaches the lowest position
The period of oscillation of a simple pendulum of length $L$ suspended from the roof of a vehicle which moves without friction down an inclined plane of inclination $\alpha$, is given by
For a simple pendulum the graph between $L$ and $T$ will be.
At which position in the string of simple pendulum has maximum tension ?
