Question

A book of mass $980\text{g}$ is placed on a table. Calculate the force exerted on the book in gravitational metric system in $\text{kgf}$.

• A. 0.98

Answer 1

The correct option is A 0.98
Given:
The mass of the book, $\text{m}=980\text{g}=0.98\text{kg}$
Force exerted on the book in gravitational metric system = Weight of the book = $0.98\times 9.8=9.604\text{N}$
Also, $1\text{kgf}=9.8\text{N}$
$⟹9.604\text{N}=\frac{9.604}{9.8}=0.98\text{kgf}$
