------------------------------------------------ If an object has a mass of 20 kg, what is the force of gravity acting on it on Earth?

A. 32.67 N
B. 2.04 kg
C. 196 N
D. 1.96 kg

The force of gravity on an object with a mass of 20 kg on Earth is calculated using the equation w = mg, where g is 9.80 m/s^2. The correct answer is 196 N.

Therefore, the correct option is c.

Explanation:

The question asks about the force of gravity acting on an object on Earth.

The force of gravity is also known as the weight of the object and can be calculated using the equation w = mg, where w is the weight, m is the mass of the object, and g is the acceleration due to gravity on Earth.

Given that the mass of the object is 20 kg and the acceleration due to gravity (g) on Earth is 9.80 m/s2, we can calculate the weight as follows:

w = mg

= (20 kg)(9.80 m/s2)

= 196 N

Therefore, the correct answer to the question is c) 196 N.
