Law of gauss

1.Consider a disc of radius R with surface charge density σ(r, θ) =[ 2cos(θ)/r^ 2]+ [1C/πR^2].a) What is the electric field flow through a closed surface S that completely encloses the disc?
b) Now a point load of -1C is placed near the surface S, but outside it. What will be the total electric field flow through S in that situation?
(S still contains the charged disk)
(c) If the point charge is now introduced into the surface S, what will be the electric field flow through the surface S?
(S contains the disk and the point load)

Write down the problem step by step.

    A hollow sphere of radius a has uniform surface charge density σ and is centered at the origin. It sits inside a bigger sphere, also centered at the origin, with radius b > a and uniform surface charge density −σ. Because of the spherical symmetry, the electric field will have the form () = E(r) r̂, where negative E(r) corresponds to an electric field pointing towards the origin, and positive E(r) corresponds to a field pointing away. What is E(r)...
