Vedclass · Answer

(C) The correct answer is $(C)$.An object remains at rest if the net force acting on it is zero.This does not mean that no forces are acting on the object; rather,it means that the vector sum of all individual forces acting on the object is zero.$\vec{F}_{	ext{net}} = \vec{F}_1 + \vec{F}_2 + \vec{F}_3 + \dots + \vec{F}_n = 0$.For example,a book resting on a table is acted upon by gravity (downward) and the normal force (upward),which balance each other.
