Suppose that a long, straight horizontal passage of a cave passes under a gravity survey area. The cross section of this passage is shown in Figure 9_50. Calculate the gravity variation that you would expect to measure along a profile on the land surface passing over the cave passage. Use a horizontal cylinder to represent the cave.
