Answer :
To solve the problem, we use the formula for the force of gravity acting on an object:
[tex]$$
F = m \times g
$$[/tex]
where
- [tex]$m$[/tex] is the mass of the object,
- [tex]$g$[/tex] is the acceleration due to gravity on Earth.
Given that the mass is [tex]$20\,\text{kg}$[/tex] and the acceleration [tex]$g$[/tex] is [tex]$9.8\,\text{m/s}^2$[/tex], we substitute these values into the formula:
[tex]$$
F = 20 \times 9.8 = 196\,\text{N}
$$[/tex]
Thus, the force of gravity acting on the object is [tex]$196\,\text{N}$[/tex].
Therefore, the best answer is:
D. [tex]$196\,\text{N}$[/tex]
