2000m Not to scale (d) The diagram shows a standard kilogram mass at the surface of the Earth and a spherical region S of radius 2000 m with its centre 4000 m from the surface of the Earth. The density of the rock in this region is 2800 kgm3. What force does the matter in region S exert on the standard mass? (e) If region S consisted of oil of density 900 kg m instead of rock, what differ- ence would there be in the force on the standard mass? (f) Suggest how gravity meters may be used in oil prospecting. Find the uncertainty within which the acceleration of free fall needs to be measured if the meters are to detect the (rather large) quantity of oil stated in (e). (G = 6.67 x 10 "Nm kg 2) [C, '91]
