Two persons A and B perform same amount of work in moving a body through a certain distance d with application of forces acting at angles 45° and 60° with the direction of displacement respectively. The ratio of force applied by person A to the force applied by person B is 1x. The value of x is _________.

Solution

Given, W1=W2 and, we know that work done is a scalar quantity it means, F1Scos45°=F2Scos60°⇒F1F2=12=1x⇒x=2.
