A geologist searching for oil finds that the gravity at a certain location is 8 parts in 107 smaller than average. Assume that a deposit of oil is located 1700m directly below. Estimate the size of the deposit, assumed spherical. Take the density (mass per unit volume) of rock to be 3000 kg/m3 and that of oil to be 800 kg/m3.
