Solution
The correct option is A 2700 J
Forces are in the same direction, hence net force will be sum of these two forces.
Net force F = 85 N + 65 N = 150 N
Displacement s = 18 m
Net work done =F×s=150×18=2700 J
2700 J
Forces are in the same direction, hence net force will be sum of these two forces.
Net force F = 85 N + 65 N = 150 N
Displacement s = 18 m
Net work done =F×s=150×18=2700 J
