Question:

The solid surface of the earth has a density of about 3000 kg/m³. A spherical deposit of heavy metals with a density of 8000 kg/m³ and radius of 1000 m is centered 2000 m below the surface. Find ∆g/g at the surface directly above this deposit, where ∆g is the increase in the gravitational field due to the deposit.
