Answer:
A. book on hand - NA
B. hand on book - upwards
C. floor on book - NA
D. earth on book - downwards
Explanation:
Since book is holding in hand so at equilibrium position we can say that the forces on the book must be in equilibrium
so first of all the force of attraction due to earth on the book is downwards and this is counterbalanced by the force of hand on book which is upwards.
