Answer :
We can find the force of gravity acting on an object by using the formula
$$
F = m \times g,
$$
where:
- $m$ is the mass of the object,
- $g$ is the gravitational acceleration on Earth.
Here, the mass is given as
$$
m = 20\, \text{kg},
$$
and the gravitational acceleration on Earth is approximately
$$
g = 9.8\, \text{m/s}^2.
$$
Substitute the given values into the formula:
$$
F = 20\, \text{kg} \times 9.8\, \text{m/s}^2 = 196\, \text{N}.
$$
Thus, the force of gravity acting on the object on Earth is $196\, \text{N}$.
The correct answer is B.
