Question

Why is the net force on an object zero if the two forces acting on it in opposite directions are equal?

Answer 1

If 2N acts on either side of a body they cancel each other.i.e.2-2=0

Answer 2

Answer:

As the two forces acting on an object are equal and opposite they neutralize each other's forces and hence the net force is zero.

Explanation:

For Eg: Force acting towards left is 10, force acting towards right is 10

Therefore one force is (-10) and other is (+10). So, -10+10=0
