a 10 N force pushes a body northward while a 15 N force acting at the same point of the body pushes it southward. Find equilbrant of these two forces.
do I add or subtract?
what about direction
South is the 180 degree opposite of north. You subtract to get the vector sum in this case.
A 5 N force in the north direction will obviously create balance.
That is what the equilbrant does.
