IMPORTANT

A small ball is suspended by a thread of length l=1 m at the point O on the wall, forming a small angle α=2° with the vertical (as shown in figure). Then the thread with the ball was deviated through a small angle β=4° and set free. Assuming the collision of the ball against the wall to be perfectly elastic, find the oscillation period of such a pendulum. (Take g=π2 m s-2)

IMPORTANT

Two light strings each of length l, are fixed at point A and B on a  fixed horizontal rod xy. A small bob is tied by both strings and in equilibrium, the strings are making angle 45° with the rod. If the bob is slightly displaced normal to the plane of the strings and released, then the period of the resulting small oscillation will be:

Pendulum A is a physical pendulum made up of thin rigid and uniform rod whose length is L. One end of this rod is attached to the ceiling by a frictionless hinge so that rod is free to swing back and forth. Pendulum B is a simple pendulum whose length is also L. The ratio ΤATB for small angular oscillations is
