A uniform solid cylinder of mass m and r...

A uniform solid cylinder of mass m and radius 2R rests on a horizontal table. A string attached to it passes over a pulley (disc) of mass m and radius R that is mounted on a fricitonaless axle through its centre . A block of mass m is suspended from the free end of the spring . The string does not slip over the pulley surface and the cylinder rolls without slipping on the table.

Force of friction acting on the cylinder is

A

`(2mg)/(3)`

B

`(3mg)/(2)`

C

`(mg)/(3)`

D

`(mg)/(6)`

A uniform solid cylinder of mass M and radius 2R rests on a horizontal table top. A string attached to it runs over a pulley (disc) of mass M and radius R thatis mounted on a frictionless axle through its centre. A block of mass M is suspended from the free end of the string. The string doesn't slip over the pulley surface, and the cylinder rolls without slipping on the, table top. Find the acceleration of the block. [g/3]

A uniform disc of mass M and radius R is mounted on a fixed horizontal axis. A block of mass m hangs from a massless string that is wrapped around the rim of the disc. The magnitude of the acceleration of the falling block (m) is

A disc of mass m and radius r is free to rotate about its centre as shown in the figure. A string is wrapped over its rim and a block of mass m is attached to the free end of the string. The system is released from rest. The speed of the block as it descends through a height h, is :-

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

Figure shows two blocks of mass m and m connected by a string passing over a pulley. The horizontal table over which the mass m slides is smooth. The pulley (uniform disc) has mass m and it can freely rotate about this axis. Find the acceleration of the mass m assuming that the string does not slip on the pulley.

Two blocks are connected by a string that passes over a pulley of radius R and moment of inertia I . The block of mass m_(1) sides on a frictionless, horizontal surface, the block of mass m_(2) is suspended from the string. Find the acceleration a of the blocks and the tension T_(1) and T_(2) assuming that the string does not slip on the pulley.

A uniform disc of radius R and mass M is free to rotate about a fixed horizontal axis perpendicular to its plane and passing through its centre. A string is wrapped over its rim and a block of mass m is attached to the free end of the string. The block is released from rest. If string does not slip on the rim then find the acceleration of the block. Neglect the mass of the string.
