1. The problem statement, all variables and given/known data There is a Uniformly charged Non conducting Spherical shell along with a point charge external to the shell . they make up an isolated system . Find the electric field inside the shell . 2. Relevant equations 3. The attempt at a solution Actually using superposition principle we obtain that the field is actually non zero . But in order to calculate the electric field inside the shell if i use gauss law by considering a gaussian surface inside the shell .... there will be no charge enclosed in it so by gauss law the flux is zero . since in that case ∫E.da = E∫da which is equal to zero . Since ∫da is non zero E must be zero ....... I guess there is some fault with this but im unable to find it out . So plz can u help me . And thanks for sparing ur valuable time to read this .
