When searching for gold, measurements of g can be used find regions within the Earth where the density is larger than that of normal soil. Such measurements can also be used to find regions in which the density of the Earth is smaller than normal soil; such regions might contain a valuable fluid (oil). Consider a deposit of oil that is 380 m in diameter and just below the surface of the Earth. For simplicity, assume the deposit is spherical. Estimate the change in the magnitude of the acceleration due to gravity on the surface above this deposit. Assume that the density of the oil is 1320 kg/m3 and the density of normal soil and rock is 2260 kg/m3. Note: Companies that search for valuable minerals actually use this method.
