Two forces of magnitude 20 N and 10 N are acting on a box in the opposite direction. What is the magnitude of the net force acting on the box?
10 N
5 N
15 N
30 N
If two people are applying 10 N and 20 N force respectively on an object on opposite directions, what is the net force? Is it 10 N or -10 N ?
The two forces equal in magnitude but acting opposite in direction on a body are called unbalanced forces.
