Select the best answer for the question.

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

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

Answer :

Sure! Let's solve this step-by-step.

To find the force of gravity acting on an object, you can use 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 on Earth (approximately [tex]\( 9.81 \, \text{m/s}^2 \)[/tex]).

Given:
- The mass [tex]\( m \)[/tex] of the object is [tex]\( 20 \, \text{kg} \)[/tex].
- The acceleration due to gravity [tex]\( g \)[/tex] is [tex]\( 9.81 \, \text{m/s}^2 \)[/tex].

We substitute these values into the formula:

[tex]\[ F = 20 \, \text{kg} \times 9.81 \, \text{m/s}^2 \][/tex]

[tex]\[ F = 196.2 \, \text{N} \][/tex]

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

The best answer is:
C. 196 N

Answer: 196 N

20x9.8=196
