Answer :
To find the force of gravity acting on an object with a mass of 20 kg on Earth, you can use the formula for gravitational force:
[tex]\[ \text{Force of gravity} = \text{mass} \times \text{acceleration due to gravity} \][/tex]
On Earth, the acceleration due to gravity is approximately [tex]\( 9.8 \, \text{m/s}^2 \)[/tex].
1. Identify the mass: The mass of the object is 20 kg.
2. Use the acceleration due to gravity: On Earth, it 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]
The force of gravity acting on the object on Earth is [tex]\( 196 \, \text{N} \)[/tex].
Therefore, the correct answer is:
D. 196 N
