                  We can shield a charge from electric fields by putting it inside a hollow conductor. Can we shield a body from the gravitational influence of nearby matter by putting it inside a hollow sphere or by some other mean?

Answer:

                  Since gravitational force is independent of the intervening medium between two bodies. therefore, we cannot shield a body from the gravitational influence of nearby matter by putting it inside a hollow sphere or by some other means.
