question

Geologists on a plane are attempting to locate the exact position of the iron reserves in a region by measuring the variation of g in the area, since a large mass of iron will exert an appreciable additional gravitational attraction on a body in the vicinity. They hover above selected spots and observe the movement of a mass suspended from a light spring. If the system has a natural period of 2 s, and the smallest movement of the mass which can be detected is 10^-6 m, what is the minimum change in g which they can observe?
