Answer :
Final answer:
The force of gravity acting on an object on Earth can be calculated using the equation F = mg, where F is the force, m is the mass of the object, and g is the acceleration due to gravity.
Explanation:
The force of gravity acting on an object on Earth can be calculated using the equation F = mg, where F is the force, m is the mass of the object, and g is the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s². Therefore, the force of gravity acting on an object with a mass of 20 kg would be:
F = 20 kg imes 9.8 m/s² = 196 N.
So, the correct answer is C. 196 N.
