Question

Select the correct answer.

Answer 1

Answer: C.  The mass of the object will be the same on both planets.

Explanation:

Let's start by explaining that mass and weight are:

Mass $m$ is the amount of matter that exists in a body, which only depends on the quantity and type of particles within it. This means mass is an intrinsic property of each body and remains the same regardless of where the body is located.  

On the other hand, weight $W$ is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass $m$ of the body by the acceleration due gravity $g$:  

$W=m.g$  

Then, since the Earth and Neptune have different values ​​of acceleration due gravity, the weight of an object in each place will vary, but its mass will not. In fact, the mass will remain the same.
