... infinitely small dΩ. The relative masses in the cone δm1 and δm2 satisfy δm1/δm2 = (r1/r2)2. The gravitational forces are proportional to δm1/r12 and δm2/r22, and therefore equal, but of opposite sign. Hence the matter in the cone does not contribute any net force at the location ~ r. If we sum over ...
