A block of mass m rests on a rough horizontl surface as shown in figure (a) and (b). Coefficient of friciton between block and surface is `mu`. A force F-mg acting at an angle `theta` with the vertical side of the block. Find the condition for which block will move along the surface.

A block of mass M rests on a rough horizontal surface as shown. Coefficient of friction between the block and the surface is mu . A force F=mg acting at angle theta with the vertical side of the block pulls it. In which of the following cases the block can be pulled along the surface?

A cubical block of mass 'm' rests on rough horizontal surface. mu is coefficient of static friction between block and the surface. A force "mg" acting on cube at an angle " theta " with vertical side of cube pulls the block. If the block is to be pulled along the surface then the value of cot (theta//2) is
