Homework Statement
If the electric field of a point charge were proportional to 1/(r^3) instead of 1/(r^2), would Gauss's law still be valid? Explain reasoning.
Homework Equations
The Attempt at a Solution
Considered a spherical Gaussian surface centered on a single point charge.
Homework Statement
A certain region of space bounded by an imaginary closed surface contains no charge.
Is the electric field always zero on the surface? If not, under what circumstances is it zero on the surface?
