Problem P. 3786. (March 2005)

P. 3786. J. F. Jolly (1809-1884), a Munich teacher of physics, measured with his very sensitive self-made balance that at a depth of 5.3 m the weight of a body is greater by one and a half millionth than that on the surface. How can that be reconciled with Newton's gravitational law?
