1Q1 .. stupid question ... the field outside a spherical conductor varies with distance .. how can it be constant :P
1. why is electric flux outside spherical conductor Q/2ε and not Q/ε
2. force exerted on Q1 (given is a spherical shell with charge q distributed uniformly on it and Q1 is at its centre) and a charge q2 some dist away
=0 why???
3. Force exerted by the spherical shell on central charge is:
towards the right. Why???
Qs 2 and 3 are given in HCV objective 1 chapter:Gauss theorem . The answers are as given in the book
