A book weighs 4N. When held at REST in your hands, the Net Forceon the book is?
0N
0.4N
39N
Or none of the above?
Force = mass*acceleration
Since the book is at rest in your hands and not moving, the net force is 0.
0n
To find the net force on the book when it is held at rest in your hands, we need to consider the forces acting on it.
When an object is at rest, the net force acting on it is zero, according to Newton's first law of motion (also known as the law of inertia). In this case, the book is held at rest in your hands, so the net force on the book is 0N.
Therefore, the correct answer is 0N.
