A uniform disc of radius R, is resting on a table on its rim. The coefficent of friction between disc and table is `mu`(show in the figure). Now the disc is pulled with a force F . What is the maximum value of F for which the disc rolls without slipping?

A disc spinning clockwise about its axis with angular velocity omega_0 is set on a rough horizontal plane[Fig.]. What is the force of friction after rolling without slipping starts? .

A disc of radius R is rotating with an angular speed omega_0 about a horizontal axis. it is placed on a horizontal table. The coefficient of kinetic friction is mu_k . Which force is responsible for the effects in what happens to the linear velocity of a point on its rim when placed in contact with the table? and What happens to the linear speed of the centre of mass when disc is placed in contact with the table?

A disc of radius R is rotating with an angular speed omega_0 about a horizontal axis. it is placed on a horizontal table. The coefficient of kinetic friction is mu_k . Calculate the time taken for the rolling to begin.

A disc rotating about its axis with angular speed omega_0 is placed lightly (without any translational push) 011 a perfectly frictionless table. The radius of the disc is R. What are the linear velocities of the points A, B and C on the disc shown in Fig. 7.41? Will the disc roll in the direction indicated ?

A circular copper disc 10 cm in radius rotates at 20pi rad/s about an axis through its centre and perpendicular to the disc. A uniform magnetic field of 0.2 T acts perpendicular to the disc. Calculate the potential difference developed between the axis of the disc and the rim.

A disc of radius R is rotating with an angular speed omega_0 about a horizontal axis. it is placed on a horizontal table. The coefficient of kinetic friction is mu_k . What condition should be satisfied for rolling to begin?

A disc of radius R is rotating with an angular speed omega_0 about a horizontal axis. it is placed on a horizontal table. The coefficient of kinetic friction is mu_k . What was the velocity of its centre of mass before being brought in contact with the table?

A 4 kg block A is placed onn 8 kg block B which rests on a smooth table,A just slips on when a force of 12 N is applied on A.What is the maximum horizontal force ,F required to make bothy A and B move together?

A metal disc is winging freely between the poles of an electromagnet, as shown in the figure. When the electromagnet is switched on, the disc comes to rest after a few oscillations. Use Faraday's law of electromagnetic induction to explain why an e.m.f. is induced in the disc.

A copper disc of radius 10 cm placed with its plane normal to a uniform magneic field completes 1,200 rotations per minute. If induced e.m.f. between the centre and edge of the disc in 6.284 m V, find the intensity of the magnetic field Take pi = 3.142
