A boy drags a bag of rice along a smooth horizontal floor with a force of 2N applied at the angle of 60o to the floor. The work done after a distance of 3m is

Answer Details

Effective component of the force along the horizontal = F cos 60o Work done by this force : 60 F cos 60 x X = 2 x 0.5 x 3 = 3J
