Vedclass · Answer

(B) The statement is False.When a body is at rest or in uniform motion,it does not mean that no force acts on it. Rather,it means that the net (resultant) external force acting on the body is zero.For example,consider a book at rest on a horizontal table:$(1)$ The gravitational force (weight,$W = mg$) acts on the book in the downward direction.$(2)$ The normal force $(N)$ exerted by the table acts on the book in the upward direction.Since the book is at rest,by Newton's first law of motion,the net force must be zero. Therefore,the normal force and the weight must be equal in magnitude and opposite in direction $(N = W)$.Thus,multiple forces act on the body,but their vector sum is zero.

When a body is at rest or in uniform motion,no force acts on it. Is this statement true or false?
