Electrons in Rutherford's gold foil experiment

Why does Coulomb's constant have units?

Why is there no permittivity-type constant for gravitation?

Why do same/opposite electric charges repel/attract each other, respectively?

Why are so many forces explainable using inverse squares when space is three dimensional?

How is Gauss' Law (integral form) arrived at from Coulomb's Law, and how is the differential form arrived at from that?

Can Maxwell's equations be derived from Coulomb's Law and Special Relativity?
