Question

Find the gravitational force that the earth exerts on a 10.0 kgmass if it is placed at the following locations. Consult the figure 12.9 in the textbook, and assume a constant density through each of the interior regions (mantle, outer core, inner core), but not the same density in each of these regions. Use the graph to estimate the average density for each region.(a) at the surface of 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 of the earth.

I got the answers for (a) and (d) but i need help with part (b) and (c)?? Thank you!!

Explanation / Answer

the mass of the earth is M

the mass of the object is m = 10.0 kg

let r be the distance of the object from the center of the earth

the gravitational force is

F = (GMm/r^2)

where G = 6.67 x 10^-11 Nm^2/kg^2
