Select the best answer for the question.

If an object has a mass of 20 kg, what is the force of gravity acting on it on Earth?

A. 1.96 kg
B. 2.04 kg
C. 196 N
D. 3267 N

Answer :

To determine the force of gravity acting on an object, we use Newton's formula for gravitational force:

[tex]$$
F = m \times g
$$[/tex]

where
[tex]\( m \)[/tex] is the mass of the object and
[tex]\( g \)[/tex] is the acceleration due to gravity.

Given:
[tex]\( m = 20 \, \text{kg} \)[/tex]
[tex]\( g = 9.8 \, \text{m/s}^2 \)[/tex]

Substitute these values into the formula:

[tex]$$
F = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 196 \, \text{N}
$$[/tex]

Thus, the force of gravity acting on the object is [tex]\( 196 \, \text{N} \)[/tex].

The best answer is option C.
