An iron ball of mass `m`, suspended by a light inextensible string of length `l` from a fixed point `O`, is shifted by `theta_(0)` as shown so as to strike the vertical wail perpendicularly.The maximum angle made by the string with vertical after the first collision, if `e` is the coefficient of restitution, is

An iron ball of mass m , suspeneded by a light inextensible string of length l from a fixed point O , is shifted by an angle ._(0) as shown so as to strike the vertical wall perpendicularly. The maximum angle made by the string with vertical after the first collision ( e is the coefficient of restitution). is_______

A steel ball is suspended by a light in extensible string of length l from a fixed point O . When the ball is in equilibrium it just touches a vertical wall as shown in the figure. The ball is first taken aside such that string becomes horizontal and then released from rest. If coefficient of restitution is e, then find the maximum deflection of the string after nth collision.

A bob of mass m suspended by a light inextensible string of length 'l' from a fixed point. The bob is given a speed of sqrt(6gl) . Find the tension in the string when string deflects through an angle 120^@ from the vertical.
