Question

The gravitational field inside the earth is proportional to

Answer 1

Answer:

The gravitational field inside the earth is proportional to distance from the center.

Explanation:

The gravitational force on a mass m at the Earth’s surface r=rE is mg, it follows immediately that in the mine the gravitational force must be

F=mgr/rE. .

So there’s no force at all at the center of the Earth-- the masses are attracting equally in all directions.

Answer 2

The gravitational field inside the earth is proportional to the distance.

• This distance is the radius, that is, the distance of the mass from the center of the earth.
• The gravitational field is the gravitational power per unit mass that would be applied to a little mass.
• It is a vector field and points towards the power that the mass would feel.
• The gravitational field at the center of the earth is zero.
