Question

Two boys exerts forces of 40 N and 60 N in opposite directions on an object. The resultant force is:

Answer 1

Let Force F_A be 40 N, and Force F_B be 60 N.
The forces are acting in opposite directions. So, the net force will act in the direction of larger force, i.e., Force, F${}_B$.
Net force = F_B - F_A = 60 - 40 = 20 N
Therefore, the resultant force is a force of 20 N acting in the direction of the larger force.
