# A book is at rest on top of a table. Which of the following is correct?

$\begin{array}{1 1} (a)\;\text{There is no force acting on the book.} \\ (b)\; \text{The book has no inertia.} \\ (c)\; \text{There is no force acting on the table.} \\ (d)\; \text{The book is in equilibrium.} \end{array}$

Among the given options book is in equilibrium. If the book is kept on a flat table then the forces acting on the book are Balanced in nature. The weight of the book(=mg) acting downwards and the Normal Reaction acting upwards. The balanced nature of these 2 forces causes book to stay still on the table
