A person pushes a block of mass 4 kg up a frictionless inclined plane 10 m long and that makes an angle of `30^@` with the horizontal . Then the work done is

A block of mass 2 kg rests on a rough inclined plane making an angle of 30° with the horizontal. If mu_(S)= 0.6 , what is the frictional force on the block ?
