If Coulomb's law involved 1 r 3 dependence (instead of 1 r 2 ), where r is distance between two point changes would Gauss's law still be true?

The dependance of solid angle on radius r is given by d ω = d s cos θ r 2 and not equal to d s cos θ r 3 Solid angle is that angle an arbitrary area makes at a point P. Gauss's law which happens to be an equivalent of Coulomb's law will not hold true if, Coulomb's law involved 1 r 3 dependance instead of 1 r 2 dependance.
