The work done will be 4 N.if the body is displaced in the same direction of the force, it will be positive.
Work done is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.
Work may be zero, positive, and negative.it depends on the direction of the body displaced.
The given data in the problem is;
F is the force applied by the worker,F=8.0 newtons
d is the displacement = 0.50 meters
The net work done is found as;
W=F×d
W=8.0 ×0.50
W=4 N
Hence,the net work done will is 4 N.
