Answer :
To determine the force of gravity acting on an object on Earth, we can use the equation:
[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.
In this case:
- The mass [tex]\( m \)[/tex] is given as 20 kg.
- The acceleration due to gravity [tex]\( g \)[/tex] on Earth is approximately 9.8 m/s[tex]\(^2\)[/tex].
Substituting the given values into the equation, we have:
[tex]\[ F = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]
Multiplying these values, we get:
[tex]\[ F = 196 \, \text{N} \][/tex]
Therefore, the force of gravity acting on an object with a mass of 20 kg on Earth is 196 N.
So, the correct answer is:
C. 196 N
[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.
In this case:
- The mass [tex]\( m \)[/tex] is given as 20 kg.
- The acceleration due to gravity [tex]\( g \)[/tex] on Earth is approximately 9.8 m/s[tex]\(^2\)[/tex].
Substituting the given values into the equation, we have:
[tex]\[ F = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]
Multiplying these values, we get:
[tex]\[ F = 196 \, \text{N} \][/tex]
Therefore, the force of gravity acting on an object with a mass of 20 kg on Earth is 196 N.
So, the correct answer is:
C. 196 N
