Question

A spherical surface completely surrounds a collection of charges. Find the electric flux through the surface if the collection consists of each of the following.

(a) a single +3.70 10-6 C charge
N·m2/C

(b) a single -2.90 10-6 C charge
N·m2/C

(c) both of the charges in (a) and (b)
N·m2/C

Answer 1

flux=integral E.dA and over a closed surface this is eual to the enclosed charge divided by permitivity.
