A plank of mass `m_(1)` with a uniform solid sphere of mass `m_(2)` placed on it rests and a force `F` is applied to the plank. The acceleration of the plank provided there is no sliding between the plank and the sphere is `(F/(m_(1)+n/7m_(2)))` then the value of `n` is

A plank of mass m_1 with a uniform sphere of mass m_2 placed on it rests on a smooth horizontal plane. A constant horizontal force F is applied to the plank. With what acceleration will the plank and the centre of the sphere move provided there is no sliding between the plank and the sphere?

A plank of mass m_(1) with a sphere of mass m_(2) on it rests on a smooth horizontal surface. A canstant horizontal force F is applied to the plank. With what sliding between the plank and the sphere? [hint: Rel vel. Of the lowest point v-(2) + epsilonR -v_(1) =0 for no sliding)

A plank with a uniform sphere placed on it rests on a smooth horizontal plane. The plank is pulled to the right by a constant force F . It the sphere does not slip over the plank, then

A plank of mass M is placed on a rough horizontal force F is applied on it A man of mass m rens on the plank find the acceleration of the man so that the plank does not move on the surface . The coefficent of friction between the plank and the surface is mu Assume that the man does not slip on the plank

A block of mass m is placed in equilibrium on a moving plank. The maximum horizontal acceleration of the plank for mu=0.2 is:
