Answer :
To find the force of gravity acting on an object with a mass of 20 kg on Earth, you can use the formula:
[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].
Step-by-step solution:
1. Identify the mass of the object:
The mass [tex]\( m \)[/tex] is given as [tex]\( 20 \, \text{kg} \)[/tex].
2. Know the acceleration due to gravity on Earth:
The acceleration due to gravity [tex]\( g \)[/tex] is [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].
3. Substitute these values into the formula:
[tex]\[ F = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]
4. Calculate the force:
[tex]\[ F = 196 \, \text{N} \][/tex]
Therefore, the force of gravity acting on the object is 196 Newtons.
So, the best answer is: D. 196 N.
