    How would the electric field vector vary at a large distance

    Hello! Oh I'm so sorry, I'm new so I didn't know. Well if the charge is zero, how does the field exist? Because the expression of electric field itself has the "Q" term. The answer is that the electric field must vary by d^-1. I'm still not able to solve :((

    How would the electric field vector vary at a large distance

    [ Moderator note- Edited to re-insert formatting template headers] Hi guys, I am stuck at this problem, Homework Statement Here it is given that an insulating sphere of radius a, carries a charge density ρ=ρ'( a^2-r^2)cosθ, when r <a. How will the leading order term for the electric field at...
