A uniform sphere A with radius R exerts a force F on a
small particle B situated at a distance 2R from the centre
of the sphere. A spherical portion of diameter R is cut
from the sphere A as shown in the figure. If F′ is the
new gravitational force between the remaining part of
the sphere A and the particle B then the correct relation
between F and F′.
