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

The acceleration of the ring is `(2g cos theta)/(1+2 cos^(2) theta)`

B

The acceleration of the block is `(2g)/(1+2 cos^(2) theta)`

C

The tension in the string is `(2mg)/(1+2 cos^(2) theta)`

D

If the block descends with velocity `v` then the ring slides with velocity `v cos theta`

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 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 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]

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.

In Fig. a pulley is shown which is frictionless and a ring of mass m can slide on the string without any friction. One end of the string is attached to point B and to the other end, a block 'P' of mass m is attached. The whole system lies in vertical plane. Now another block 'C' of same mass m is attached to the block '13' and system is released from rest. If a_(1) and a_(2) are the magnitudes of initial accelerations of ring and blocks, respectively, then

In Fig. a pulley is shown which is frictionless and a ring of mass m can slide on the string without any friction. One end of the string is attached to point B and to the other end, a block 'P' of mass m is attached. The whole system lies in vertical plane. If block 'C' mentioned above was released from some height and collided with 'P' with some velocity u , then find the velocity of the ring just after the collision. The collision is perfectly inelastic.

A block of mass m_(1) rests on a horizontal table. A string tied to the block is passed on a frictionless pulley fixed at the end of the table and to the other end of string is hung another block of mass m_(2) . The acceleration of the system is

A small ring of mass m is constrained to slide along a horizontal wire fixed between two rigid supports. The ring is connected to a particle of same mass by an ideal string & the whole system is released from rest as shown in the figure. If the coefficient of friction between ring A and wire is (3)/(5) , the ring will start sliding when the connecting string will make an angle theta with the vertical, then theta will be (particle is free to move and ring can slide only)

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

A smooth ring of mass M is threaded on a string whose ends are then threaded over two smooth fixed pulleys with masses m and m' tied on to them respectively. The various portions of strings are vertical. The system is free to move. What is the condition if M alone is to remain at rest ?
