A weight of `5N` is moved up a frictionless inclined plane from `R` to `Q` as shown.

What is the work done in joules?

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

Assertion : The work done in bringing a body down from the top to the base along a frictionless inclined plane is the same as the work done in bringing it down along the vertical side . Reason : The gravitational force on the body along the inclined plane is the same as that along the vertical side.

Statement-1 : The work done in bringing a body down from the top to the base along a frictionless incline plane is the same as the work done in brining it down from the vertical side. STATEMENT-2 : Work is defined as intvec(F) . dvec(r )
