I found the value for A which proved to be very simple, howeverthe ones involving density are giving me headaches.
Thanks in advance....
Find the gravitational force that the earth exerts on a 10.0 kgmass if it is placed at the following locations. (a) at the surfaceof the earth; (b) at the outer surface of the molten outer core;(c) at the surface of the solid inner core; (d) at the center ofthe earth.
Consult the figure 12.9 in the textbook, and assume a constantdensity through each of the interior regions (mantle, outer core,inner core), butnot the same density in each of theseregions. Use the values given below for average density for eachregion.
Assume the inner core has outer radius 1.2 × 106m, inner radiuszero and density 1.3 × 104kg/m3, the outer core has inner radius1.2 × 106m, outer radius 3.6 × 106 m and density 1.1 ×104 kg/m3,the total mass of the earth is mE = 5.97 × 1024kgand its radius is RE = 6.38 ×106m.
