The gravity of Neptune is about 1.1 times the gravity of Earth. How will the mass of an object on Neptune compare with its mass on Earth?

a. The mass of the object will be slightly less on Neptune than on Earth.

b. The mass of the object will be slightly more on Neptune than on Earth.

c. The mass of the object will be the same on both planets.

d. The mass of the object on Neptune will be 10 times the object's mass on Earth.

c. The mass of the object will be the same on both planets

Explanation:

Mass is an intrinsic property of matter that is not affected by the presence of a gravitational field.

The property of matter that is affected by gravity is its weight.

And although the weight depends on the mass of the object, when moving to another planet mass must remain the same. What changes is the acceleration that the body feels towards the planet cause by the gravitational force and therefore the weight, not the mass.

Gravity has an effect on weight, but not on mass. The mass of the object will be the same on both planets. (choice-C)
