A small trolley of mass 2kg resting on a horizontal frictionless turntable is connected by a light spring to the centre of the table. The relaxed length of the spring is 35cm. When the turntable is rotated with an angular frequency of 10 rad `s^-1`, the length of the spring becomes 40 cm. The force constant of the spring is

A copper wire of negligible mass of length 1 m and cross sectional area 10^-6 m^2 is kept on a smooth horizontal table with one end fixed. A ball of mass 1 kg is attached to the other end. The wire and the ball are revolving with an angular velocity of 20 rad.s^-1 . IF the elongation in the length of the wire is 10^-3m , obtain the Young's modulus. IF on increasing the angular velocity to 100 rad .s^-1 the wire breaks down, obtain the breaking stress.
