Dear student

First of all calculate linear mass density of chain that is equal to mass/length. next since 1/6 length is hanging the centre of mass will rise to a height of 1/12length on pulling the chain up.next work done =m*g*h=(1/6L*m/L)*g*1/12L=1/72 mgl.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
