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. 2.04 kg
D. 32.67 N

Answer :

Sure! Let's solve this step by step.

1. Understand the problem:
We need to find the force of gravity acting on an object with a mass of 20 kg on Earth.

2. Recall the formula for the force of gravity:
The force of gravity (also known as weight) can be calculated using 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,
- [tex]\( g \)[/tex] is the acceleration due to gravity.

3. Values given:
- The mass [tex]\( m \)[/tex] of the object is 20 kg.
- The acceleration due to gravity [tex]\( g \)[/tex] on Earth is approximately [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].

4. Perform the calculation:
Substitute the given values into the formula:
[tex]\[
F = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2
\][/tex]

5. Calculate the result:
[tex]\[
F = 196 \, \text{N}
\][/tex]

Therefore, the force of gravity acting on the object is 196 N (Newtons).

So, the correct answer is:
A) 196 N
