A block is pulled a distance x along a rough horizontal table by a horizontal string. If the tension in the string is T, the weight of the block is W, the reaction is N and frictonal force is F. Write down expressions for the work done by each of these forces.

A particle is pulled a distance l up a rough plane inclined at an angle alpha to the horizontal by a string inclined at an angle beta to the plane (beta +alpha lt 90^@) . If the tension the string is T, the normal reaction between the particle and plane is N, the frictional force is F, and the weight of the particle is w . write down expression for the work done by each of forces.
