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

A. 32.67 N
B. 2.04 kg
C. 1.96 kg
D. 196 N

Answer :

To find the force of gravity acting on an object, we can use the formula:

[tex]\[ \text{Force of gravity} = \text{mass} \times g \][/tex]

where [tex]\( g \)[/tex] is the acceleration due to gravity on Earth, which is approximately [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].

In this case, the mass of the object is 20 kg. So we can plug these values into the formula:

1. Mass of the object = 20 kg
2. Acceleration due to gravity = [tex]\( 9.8 \, \text{m/s}^2 \)[/tex]

Using the formula:

[tex]\[ \text{Force of gravity} = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]

[tex]\[ \text{Force of gravity} = 196 \, \text{N} \][/tex]

Therefore, the force of gravity acting on the object on Earth is 196 N.

The best answer for the question is option D: 196 N.
