A plank of mass M is placed on a rough horizontal surface. A man m walks on the plank with an acceleration 'a' while the plank is also acted upon by a horizontal force F whose magnitude and direction can be adjusted to keep the plank at rest. The coefficient of friction between plank and surface is mu . Choose the correct options. .

A plank of mass 3m is placed on a rough inclined plane and a man of mass m, the coefficient of friction between the board and inclined plane is mu = 0.5 , the minimum acceleration of man so that plank does not slide is :

In the figure shown, a solid sphere of mass 'm' and radius r is released from a height 6r to slide down a smooth surface. A plank of same mass 'm' touches the horizontal portion of the surface at the ground. The co-efficient of friction between the plank and the sphere is mu and that between the plank and the ground is mu//4 . Find the work done by the friction force between the plank and the ground till the sphere starts pure rolling on the plank. Neglect the height of the plank.
