Answer :
To find the force of gravity acting on an object on Earth, you can use the formula for weight:
[tex]\[ \text{Weight} = \text{mass} \times \text{gravitational acceleration} \][/tex]
1. Identify the known values:
- Mass ([tex]\(m\)[/tex]) of the object: 20 kg
- Gravitational acceleration ([tex]\(g\)[/tex]) on Earth: approximately 9.8 m/s²
2. Substitute the values into the formula:
[tex]\[ \text{Weight} = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]
3. Calculate the result:
[tex]\[ \text{Weight} = 196 \, \text{N} \][/tex]
Therefore, the force of gravity acting on the object is 196 N. The correct option is B) 196 N.
