Hi!
Please see the attached file for complete solution.
Like the electrostatic force, the gravitational force obeys an inverse square law.
Thus, Gauss' law is applicable to gravitational fields as well.
Gauss' law states that the flux through a closed surface (a surface that encloses a volume) is proportional to the field source (in an electrostatic field, the source is the charge; in a gravitational field, the source is the mass).
Therefore we can ...
