State Gauss.s law of electrostatics. Using it, derive Coulomb.s law.

State Gauss.s law in electrostatics.

State Gauss's law of electrostatics. Using it derive field due to a uniformly charged thin spherical shell.

State Gauss.s law of electrostatics and write down its mathematical form with identification of the symbols. Derive Coulomb.s law from Gauss.s law.

Define Raoult’s law.

State Coulomb.s law in electrostatics and hence define units of charge in CGS (ESU) and SI system. Derive the relation between coulomb and stat-coulomb?
