A block of mass 2 kg rests on an inclined plane which makes an angle of 30^(@) with the horizontal. The coefficient of friction between the block and the surface is sqrt(3//2) . (i) What force should be applied on the block so that it moves down without any acceleration ? (ii) What force should be applied on the block so that it moves up without any acceleration ? (iii) Calculate the ratio of the powers in the above two cases if the block moves with uniform speed in both the cases.

A block of mass 2 kg rests on a plane inclined at an angle of 30^(@) with the horizontal the coefficient of friction between the block and the surface is 0.7 what will be the frictional force acting on the block

A block of mass 2kg rests on a rough inclined plane making an angle of 30^@ with the horizontal. The coefficient of static friction between the block and the plane is 0.7. The frictional force on the block is
