3. For a while in the early 20th century one proposed model for the structure of atoms was that a positive point charge (the nucleus) +Ze was at the center of a charged sphere of radius R and charge -Ze. To be clear, the negative charge in the sphere was proposed to be spread through the volume of the sphere, not on its surface. Z is the atomic number. (a) In terms of the symbols, Z and R, what is...
