Answer :
To determine the force of gravity acting on an object, we use the formula for weight (the force due to gravity):
$$
F = m \cdot g
$$
where
- $m$ is the mass of the object, and
- $g$ is the acceleration due to gravity on Earth.
Given:
- The mass $m = 20\,\text{kg}$
- The gravitational acceleration $g = 9.8\,\text{m/s}^2$
Substitute these 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 is $196\,\text{N}$.
The correct answer is:
B) $196\,\text{N}$
$$
F = m \cdot g
$$
where
- $m$ is the mass of the object, and
- $g$ is the acceleration due to gravity on Earth.
Given:
- The mass $m = 20\,\text{kg}$
- The gravitational acceleration $g = 9.8\,\text{m/s}^2$
Substitute these 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 is $196\,\text{N}$.
The correct answer is:
B) $196\,\text{N}$
