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

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

Answer :

To find the force of gravity acting on an object, we can 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 ([tex]\( g \)[/tex]) is approximately [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].

Given:
- The mass of the object ([tex]\( m \)[/tex]) is [tex]\( 20 \, \text{kg} \)[/tex].

Now, plug these values into the formula:

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

[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:

C) 196 N
