[" Q.5A force of "50N" acts on a body and moves it a distance of "4m" on a horizontal surface."],[" Calculate the work done if the direction of force is at an angle "60^(@)" to the horizontal "],[" surface."]

(a) What happens to the work done when the displacement of a body is at right angles to the direction of force acting on it ? Explain your answer. (b) A force of 50 N acts on a body and moves it a distance of 4 m on a horizontal surface. Calculate the work done if the direction of force is at an angle of 60^(@) to the horizontal surface.

A force of 20 N acts on a body and the body moves through 1 m at an angle of 45^(@) in the direction of the force. The work done by the force is

When a body moves on a horizontal direction the amount of work done by the gravitatioal force is

A force of 10N is acting on a block of 20kg on horizontal surface with coefficient of friction mu=0.2 . Calculate the work done by the force.

A force of 10N is acting on a block of 20kg on horizontal surface with coefficient of friction mu=0.2 . Calculate the work done by the force.

Calculate the work done if a sled is pulled forward 50m along a frictionless surface by a force of 250N at an angle of 60^@ to the horizontal.

A force F is applied on a lawn move at an angle of 60^(@) with the horizontal. If it moves through a distance x , the work done by the force is

A force of 50 N acts on an object and displaces it by 2 m. If the force acts at an angle of 60° to the direction of its displacement, find the work done.
