Can a body be in equilibrium when only one force acts on it? Explain.
Solution 1DQ Step 1 of 2: No, the body cannot be in equilibrium if only one force is acting on it, as it violates newton's second law. Equilibrium is the state of a body or physical system at rest or in unaccelerated motion in which the resultant of all forces acting on it is zero. When only one force is acting on the body, this results in nonzero net force. If some net force is acting on the body, it cannot be in equilibrium. As force results in acceleration(F=ma).
