Question

A girl is in rest state with a book of 0.6 kg on her palm. Find:
i)force exerted by earth on the book
(ii) force exerted by book on the earth
(iii) under what forces the book is in equilibrium?
Take g = 9.8 N/kg.​

Answer 1

Answer:

weight=mg =0.6*9.8=5.88N

see

2)as the book is in contact with palm at certain height no force exerted by it on the earth

1)similarly no force exerted by earth on it

3)the book is in equilibrium when the normal force exerted by the palm is equal to its force that is equal to its weight...5.88N

hope so helpful
