Select the best answer for the question.

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

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

Answer :

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

[tex]\[ \text{Force of gravity (F)} = \text{mass (m)} \times \text{acceleration due to gravity (g)} \][/tex]

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

Given:
- Mass ([tex]\(m\)[/tex]) of the object = 20 kg

To calculate the force of gravity:

1. Multiply the mass by the acceleration due to gravity:

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

2. Perform the multiplication:

[tex]\[
F = 196 \, \text{N}
\][/tex]

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

Therefore, the correct answer is A. 196 N.
