In the figure shown a thin light inextensible string is wrapped around a uniform disc. One end of the strin is fixed to the ceiling of the lift and the other end is fied to the circumference of the disc. Acceleration `'a'` of the lift is such that the centre of the disc not move with respect to ground. Find the value of `(a)/(g)`. String does not slip on pulley.

A string is wrapped over the edge a uniform disc and the free end is fixed with the ceiling. The disc moves down, unwinding the string. Find the downward acceleration of the disc.

A disc of mass M has a light, thin string wrapped several times around its circumference. The free end of string is attaced to the ceiling and the disc is released from rest. Find the acceleration of the disc and the tension in the string.

A disc of mass M has a light, thin string wrapped several times around its circumference. The free end of string is attaced to the ceiling and the disc is released from rest. Find the acceleration of the disc and the tension in the string.

A disc of mass m and radius R lies flat on a smooth horizontal table. A mass less string runs halfway around it as shown in figure. One end of the string is attached to a small body of mass m and the other end is being pulled with a force F. The circumference of the disc is sufficiently rough so that the string does not slip over it. Find acceleration of the small body.

A string is wrapped on a uniform disc and the other end of the string connected to a wall. The system is placed on a smooth plane, inclined at an angle theta , with the string parallel to the plane, as shown in the figure. The acceleration of the disc is

A disc of mass m lies flat on a smooth horizontal table. A light string runs halfway around it as shown in figure. One end of the string is attached to a particle of mass m and the other end is being pulled with a force F. There is no friction between the disc and the string. Find acceleration of the end of the string to which force is being applied.

String is wrapped over a pulley and free end is fixed to the ceiling as shown in figure. Mass of the pulley is m and its radius is R. Assume that pulley is identical to dise. Calculate acceleration of pulley as it is allowed to fall by unwinding the string. Assume that string does not slip over the pulley.
