Practicing Success
What is the force of gravity experienced by an object at the centre of the earth? (Assume that the earth is perfectly spherical) |
0 g-force 1 g-force 9.81 g-force 10 g-force |
0 g-force |
Since a body at the centre of the earth would experience equal gravitational force from all sides, the vector addition of all of these forces amount to zero. Therefore, the force experienced by an object at the centre of the earth is zero. |
