Homework Statement
what is the gravitational field intensity at the center of the earth
Homework Equations
The Attempt at a Solution
i was told that it was zero because you have the Earth's mass surrounding it, and graivty moves to the center of its mass (center of radius) therefore the net force would be zero? is this correct?
also if you sub in 0 in the gravitational field intensity formula for the radius, you get a value over zero, meaning it is undefined... so i can't really use that to support why it is zero at the center...
thanks
