Solve the following questions :
When certain weight is tied through pulley , the block gets displaced through displacement of 50cm .the work done on the block is 2500 erg then , how much force is applied on the block by weight ?

Answer the following questions: Determine the amount of work done when an object is displaced at an angle of 30^@ with respect to the direction of the applied force.

Solve the following examples: When a force of 20 N acts on a body, the body is displaced by 5 m. If the angle between the force and displacement is 60° , find the work done by the force.

Answer the following questions: Derive the expression for the work done when the displacement is in the direction of the force.
