Two masses m and 2m are attached to two ends of an ideal spring as shown in figure. When thye spring is in the compressed state, the energy of the spring is 60 J, if the spring is released, then at its natural length

Two masses m_(1) and m_(2) are attached to a spring balance S as shown in figure. m_(1) gt m_(2) then the reading of spring balance will be . .

A force of 10 N holds an ideal spring with a 20 N/m spring constant in compression. The potential energy stored in the spring is

A uniform rod of length L and mass M is pivotedat the centre. Its two ends are attached to two springs of equal spring constants. k . The springs as shown in the figure, and the rod is free to oscillate in hte horizontal plane. the rod is gently pushed through a small angle theta in one direction and released. the frequency of oscilllation is-

Two equal masses are attached to the two ends of a spring of spring constant k. The masses are pulled out symmetrically to stretch the spring by a length x over its natural length. The work done by the spring on each mass is
