Answer :
Final answer:
The gravitational force on an object having a mass of 20 kg is calculated using the formula w=mg. Substitution gives the answer as 196 N, which is option C in your question.
Explanation:
The gravitational force on an object is calculated using the formula w=mg, where 'w' represents weight or gravitational force, 'm' is the mass of the object, and 'g' is the acceleration due to Earth's gravity, which is approximately 9.80 m/s².
If we substitute the given mass of the object into this formula, we get w = (20.0 kg)(9.80 m/s²) = 196 N. Therefore, the gravitational force on an object with a mass of 20 kg is 196 N, which corresponds to option C in your question.
