Things should pop right out at you. Consider the Bouguer gravity contour map on this webpage . Find the depth to the center of the anomaly and the radius of the anomaly. For the figure shown on this webpage , calculate the Bouguer gravity anomaly at the following points assuming you can model this object as an empty sphere. What you are doing is constructing a curve similar to the one found in Figure 9-12.
All distances are in meters , by the way.
Note that these numbers will certainly be the same. Remember the mistake in Eq.
