Answer :
To find the force of gravity acting on an object with a mass of 20 kg on Earth, we use the formula:
[tex]\[ F = m \times g \][/tex]
Where:
- [tex]\( F \)[/tex] is the force of gravity (in newtons, N),
- [tex]\( m \)[/tex] is the mass of the object (in kilograms, kg),
- [tex]\( g \)[/tex] is the acceleration due to gravity on Earth (approximately [tex]\( 9.8 \, \text{m/s}^2 \)[/tex]).
Let's calculate:
1. Identify the mass: The mass of the object is 20 kg.
2. Identify the gravitational acceleration: On Earth, [tex]\( g = 9.8 \, \text{m/s}^2 \)[/tex].
3. Calculate the force of gravity:
[tex]\[ F = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 196 \, \text{N} \][/tex]
The force of gravity acting on the object is 196 newtons.
Therefore, the correct answer is B. 196 N.
