Solution
The correct option is B 10 N
Below are the forces acting on the book,
(i) Gravitational force downwards
(ii) Normal force upwards.
The direction of this normal force is exactly opposite to the gravitational force. The book remains in equilibrium if the net force acting is zero. In the above case, the book is at rest, so, the force acting on the book will also be equal to 10 N.
