Physics · LAWS OF MOTION
हिन्दीRefer to the given figure showing a book resting on a horizontal table. The weight of the book is \( W \) downward and the normal force exerted by the table is \( R \) upward. What is the net force acting on the book?
Correct answer · Option 2
Zero
Explanation
Since the book is observed to be at rest, its acceleration is zero, which implies by the first law that the net external force acting on it is zero (\( R = W \)).
