Two masses‘ m ’and ‘M’are attached to the strings as shown in the figure If the system is in equi

Two masses m and M are attched with strings as shwon . If the system is in equilibrium then , tan theta

Two masses m and M are attached with strings as shown. For the system to be in equilibrium we have.

Two bodies of masses m and 4 m are attached with string as shown in the figure. The body of mass m hanging from a string of length l is executing oscillations of angular amplitude theta_(0) while the other body is at rest. The minimum coefficient of friction between the mass 4m and the horizontal surface should be

Two masses m and 2m are attached to two ends of an ideal spring as shown in figure. When the 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 block each of mass 'm' are attached with two elastic strings as shown in the figure. Masses of strings are negligible in comparison to block of mass 'm' density of material of each string is rho . The whole system is moving vertically upward with an acceleration a = g/2. It is in equilibrium with respect to elevator. Ratio of elongation in rod 1 to that of rod 2 will be

Two block each of mass 'm' are attached with two elastic strings as shown in the figure. Masses of strings are negligible in comparison to block of mass 'm' density of material of each string is rho . The whole system is moving vertically upward with an acceleration a = g/2. It is in equilibrium with respect to elevator. Ratio of PE stored in string-1 to string-2 in equilibrium is

A mass M=5 kg is attached to a string as shown in the figure and held in position so that the spring remains unstretched. The spring constant is 200 Nm^(-1) . The mass M is then released and begins to undergo small oscillations. The amplitude of oscillation is

Two masses of 10kg and 5kg are suspended from a rigid support as shown in figure. The system is pulled down with a force of 150N attached to the lower mass. The string attached to the support breaks and the system accelerates downwards In case the force continues to act. what will be the tension acting between the two masses ? .

Two masses of 10kg and 5kg are suspended from a rigid support as shown in figure. The system is pulled down with a force of 150N attached to the lower mass. The string attached to the support breaks and the system accelerates downwards In case the force continues to act. what will be the tension acting between the two masses ? .

A big block of mass M is placed on a horizontal surface. Two cubes each of mass m are attached with ideal string-pulley system as shown in figure. On ecube falls in the groove drilled into the block as shown. Assuming all the surfaces are smooth and system is released from rest, find instantaneous power developed by gravity. (consider M=2m). Assume that the system starts moving from rest at time t = 0 .
