Answer :
To determine the force of gravity acting on an object on Earth, you can use the formula for gravitational force:
[tex]\[ F = m \times g \][/tex]
where:
- [tex]\( F \)[/tex] is the force of gravity,
- [tex]\( m \)[/tex] is the mass of the object,
- [tex]\( g \)[/tex] is the acceleration due to gravity on Earth, which is approximately [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].
Given:
- The mass ([tex]\( m \)[/tex]) of the object is [tex]\( 20 \, \text{kg} \)[/tex].
- The acceleration due to gravity ([tex]\( g \)[/tex]) on Earth is [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].
We use the given values in the formula:
[tex]\[ F = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]
This calculates to:
[tex]\[ F = 196 \, \text{N} \][/tex]
So, the force of gravity acting on an object with a mass of 20 kg on Earth is [tex]\( 196 \, \text{N} \)[/tex].
Therefore, the best answer to the question is:
D. [tex]\( 196 \, \text{N} \)[/tex]
[tex]\[ F = m \times g \][/tex]
where:
- [tex]\( F \)[/tex] is the force of gravity,
- [tex]\( m \)[/tex] is the mass of the object,
- [tex]\( g \)[/tex] is the acceleration due to gravity on Earth, which is approximately [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].
Given:

- The acceleration due to gravity ([tex]\( g \)[/tex]) on Earth is [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].

[tex]\[ F = 196 \, \text{N} \][/tex]
So, the force of gravity acting on an object with a mass of 20 kg on Earth is [tex]\( 196 \, \text{N} \)[/tex].
Therefore, the best answer to the question is:
D. [tex]\( 196 \, \text{N} \)[/tex]
