Figure shows a yo-yo placed on a rough surface friction is sufficient for pure rolling. After force F acts pure rolling begins

Statement-1: Angular acceleration of yo-yo is in clockwise sense.
Statement-2: Torque due to F must be larger than the torque due to friction.

A uniform cylinder of mass M and radius R is placed on a rough horizontal board, which in turn is placed on a smooth surface. The coefficient of friction between the board and the cylinder is mu . If the board starts accelerating with constant acceleration a, as shown in the figure, then Option1 for pure rolling motion of the cylinder, direction of frictional force is forward and its magnitude is M a / 3 Option2 the maximum value of a, so that cyliner performs pure rolling is 3 μ g Option3 The acceleration of the centre of mass of te cylinder under pure rolling condition for the given a is a / 3 Option4 none of these

A thin walled hollow spherical shell of mass m and radius r starts from rest and moves along atrack as shown in figure assume that shell successfully negotiates the loop. Statement-1: Normal reaction at A is greater when friction is absent on the track as compared to the case when sphere executes pure rolling. Statement-2: Due to frictional torque shell have larger translational velocity at A in case of pure rolling.

A force F is applied at the top of a ring of mass M and radius R placed on a rough horizontal surface as shown in figure. Friction is sufficient to prevent slipping. The friction force acting on the ring is:
