5.4.10: Bubble Inside a Uniform Solid Sphere

( \newcommand{\kernel}{\mathrm{null}\,}\)

Figure 5.11.png
FIGURE V.11

P is a point inside the bubble. The field at P is equal to the field due to the entire sphere minus the field due to the missing mass of the bubble. That is, it is

g=43πGρr1(43πGρr2)=43πGρ(r1r2)=43πGρc.

That is, the field at P is uniform (i.e. is independent of the position of P) and is parallel to the line joining the centres of the two spheres.
