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. 196 N
C. 2.04 kg
D. 32.67 N

Answer :

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

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

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

Let's calculate it step-by-step:

1. Identify the mass of the object: The mass is given as [tex]\( 20 \, \text{kg} \)[/tex].

2. Use the gravitational acceleration on Earth: This is [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].

3. Calculate the force of gravity:
[tex]\[
\text{Force of gravity} = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 196 \, \text{N}
\][/tex]

Therefore, the force of gravity acting on the object on Earth is [tex]\( 196 \, \text{N} \)[/tex]. The correct answer is option B) 196 N.
