Gauss Law

Concept: Physics (Electrostatics) - Electric Field of a Spherical Conductor.

Step 1: Calculate the total charge on the sphere. The total charge is the product of charge density and surface area : $ R E R $

Concept: Physics (Electrostatics) - Application of Gauss's Law.

Step 1: State Gauss's Law. The total electric flux ( ) through a closed surface is equal to the enclosed charge ( ) divided by the permittivity of free space ( ): $ \rho V A r 4\pi r^2 E 4\pi r^2 $

We know that, the electric field intensity outside the sheet is given by Therefore, the electric field intensity is independent of .
