Question

16. A solid sphere of uniform density and radius R
applies a gravitational force of attractional equal to
F, on a particle placed at A, distant 2R from the
centre of the sphere. A spherical cavity of radius
is now made in the sphere as hown in the figure.
The sphere with cavity now applies a gravitational
force F, on the same particle placed at A. The
ratioF2/F1
will be
