Answer :
The weight of an object on Earth is calculated using the formula
[tex]$$
W = m \times g,
$$[/tex]
where:
- [tex]$m$[/tex] is the mass of the object (in kilograms),
- [tex]$g$[/tex] is the acceleration due to gravity on Earth (in meters per second squared).
Given that the mass of the book is [tex]$15\ \text{kg}$[/tex] and the acceleration due to gravity is [tex]$9.8\ \text{m/s}^2$[/tex], we calculate the weight as follows:
[tex]$$
W = 15\ \text{kg} \times 9.8\ \text{m/s}^2 = 147\ \text{N}.
$$[/tex]
Thus, the weight of the book on Earth is [tex]$147\ \text{N}$[/tex].
