1)Will Gauss's law be fulfilled if the exponent in Coulomb's law was not exactly 2? explain why.
2)A positive point charge q is located in the center of a hollow metal sphere. What charges appear in (a) the inner surface and in (b) the outer surface of the sphere? (c) If we bring a metallic object (unloaded) to the sphere, will its responses from (a) and (b) above change? Will the way in which the charge is distributed on the sphere change?
Explain why for every incise.
