Question

The net force on an object is zero if the two forces acting on it in :

1- opposite direction

2-same direction

3-sometimes opposite and sometimes same direction

4-all of above

Answer 1

answer is 1. opposite direction
as in opposite directions the forces would cancel each other

I hope this would help:)

Answer 2

Force is a vector quantity 1 option is more convenient and it should be the right answer as the opposite vectors can cancel each other.. Vectors in the. Same direction would be additive ...so 1
