Homework Statement
A spherical insulator of radius R and charge density ρ = ρo/r2 where r is the distance from its centre. Find the electric field at a point inside and outside the insulator.
Homework Equations
EA = Qencl/εo
The Attempt at a Solution
What's throwing me off is the charge density. Setting up a gaussian sphere, I don't know what to do to find Q for the formula.
