Question
What is the force of gravity experienced by an object at the centre of the earth? (Assume that the earth is perfectly spherical)*1 point0 g-force1 g-force9.81 g-force
Solution
The force of gravity experienced by an object at the centre of the Earth is 0 g-force.
Here's why:
-
The force of gravity is the result of mass attracting other mass. On the surface of the Earth, all of its mass is pulling you towards it, which is why we feel gravity pulling us down.
-
However, at the center of the Earth, the situation is different. The mass of the Earth is all around you, not just below you.
-
This means that the gravitational forces exerted by all the mass of the Earth cancel each other out. You're being pulled equally in all directions.
-
Therefore, the net force of gravity you would experience at the center of the Earth is zero, or 0 g-force.
