7. The spherical nucleus of a cer-tain atom contains a positive charge Ze in a volume of radius R.Compare the force exerted on an electron inside the nucleus at ra-dius 0.5R with the force at radius R for a nucleus in which (a) thecharge density is constant throughout its volume, and (b) thecharge density increases in direct proportion to the radius r.

Concept used: Coulomb force is used. Coulomb force is inversely proportional to square of distance…
