Answer:
The statement is incorrect because, a force acting on an object does not necessarily have to produce motion.
People have the misconception that when a force acts on an object it always produces motion
Explanation:
The statement is incorrect because, a force acting on an object does not necessarily have to produce motion. It could be in static equilibrium where the net force is zero and produces not motion. The body could also be in dynamic equilibrium when no net force acts on it moving at a constant velocity. But here we are concerned with static equilibrium since the body does not move at all.
People have the misconception that when a force acts on an object it always produces motion and, we have seen from the above tat its not always true.
