nh A 1.8 kg book is resting on a table. The gravitational field strength = 9.8 N/kg. Calculate the weight of the book. Give your answer to 2 significant figures.

The weight of the book is 18 N

Explanation:

Mass (m) = 1.8 kg

g = 9.8 N/kg

Weight (W) = ?

Now,

W = mg

W = (1.8 kg) × (9.8 N/kg)

W = 17.64 N ≈ 18 N

Thus, The weight of the book is 18 N
