To determine the force of gravity acting on an object, we use the formula:
[tex]\[ F = m \cdot g \][/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, this is approximately [tex]\( 9.8 \ m/s^2 \)[/tex]).
Given:
- The mass [tex]\( m \)[/tex] of the object is [tex]\( 20 \ kg \)[/tex].
Using the formula:
[tex]\[ F = 20 \ kg \times 9.8 \ m/s^2 \][/tex]
[tex]\[ F = 196 \ N \][/tex]
So, the force of gravity acting on the object is [tex]\( 196 \ N \)[/tex].
Thus, the best answer is:
B. 196 N
