To determine the force of gravity acting on an object with a given mass on Earth, we 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 (in kilograms),
- [tex]\( g \)[/tex] is the acceleration due to gravity on Earth (approximately [tex]\( 9.8 \, \text{m/s}^2 \)[/tex]).
Given:
- Mass ([tex]\( m \)[/tex]) = 20 kg
- Acceleration due to gravity ([tex]\( g \)[/tex]) = 9.8 m/s²
We can calculate the force of gravity:
[tex]\[ F = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]
[tex]\[ F = 196 \, \text{N} \][/tex]
Therefore, the best answer is:
D. 196 N
