A smooth ring A of mass 4 kg can slide on a fixed smooth horizontal rod. A string tied to the ring passes over a fixed pulley and carries a block B of mass 2 kg as shown in the figure. At the initial instant, the string attached to the ring makes an angle 60° with the horizontal rod. If the system is released from rest, the initial acceleration of the ring is?

A smooth ring of mass m can slide on a fixed horizontal rod. A string tied to the ring pases over a fixed pulley B and carries a block C of mass 2m as shown below. As the ring starts sliding

A smooth ring A of mass m can slide on a fixed horizontal rod. A string tied to the ring passes over a fixed pulley B and carries a block C of ma M(=2m) as shown in figure. At an instant the string between the ring and the pulley makes an angle theta with the rod. a. Show that, if the ring slides with a pspeed v, the blockdescends with speed v cos theta , b. With whast acceleration will the ring starts moving if the system is released from rest with theta= 30^0

A ring of mass m=1kg can slide over a smooth vertical rod. A light string attached to the ring passing over a smooth fixed pulley at a distance of L=0.7m from the rod as shown in figure. At the other end of the string mass M=5kg is attached, lying over a smooth fixed inclined plane of inclination angle 37^@ . The ring is held in level with the pulley and released. Determine the velocity of ring when the string makes an angle (alpha=37^@) with the horizontal. [sin 37^@=0.6]

A ring of mass m can slide on the vertical smooth rod. Ring is connected by block with string as shown in figure. Pulley is of mass-less and smooth the system is released from reast. Initial tension in string is

One end of a light spring of natural length d and spring constant k is fixed on a rigid wall and the other is attached to a smooth ring of mass m which can slide without friction on a vertical rod fixed at a distance d from the wall. Initially the spring makes an angle of 37^(@) with the horizontal as shown in fig. When the system is released from rest, find the speed of the ring when the spring becomes horizontal. [ sin 37^(@) = 3/5]

Two bodies of masses 4 kg and 6 kg are tied to the ends of a massless string. The string passes over a frictionless pulley. The acceleration of the system is :

The smooth ring A can slide on a fixed horizontal rod as shown the pulley is fixed. If some instant velocity of ring is v, find the velocity of block at that instant.

One end of a light spring of natural length 4m and spring constant 170 N/m is fixed on a rigid wall and the other is fixed to a smooth ring of mass (1)/(2) kg which can slide without friction in a verical rod fixed at a distance 4 m from the wall. Initially the spring makes an angle of 37^(@) with the horizontal as shown in figure. When the system is released from rest, find the speed of the ring when the spring becomes horizontal.

A conducting ring of mass 2 kg and radius 0.5 m is placed on a smooth horizontal plane. The ring carries a current . A horizontal magnetic field B = 10T is switched on at time t = 0 as shown in figure. The initial angular acceleration of the ring will be:

A ring of mass m can freely slide on a smooth vertical rod. The ring is symmetrically attached with two springs, as shown, each of stiffness k . Ring is displaced such that each spring makes an angle theta with the horizontal. If the ring is slightly displaced vertically, then time period is.......
