## Homework Statement

Find the electric field of a point outside sphere without using Gauss's law. (Do not evaluate the integral)

## Homework Equations

Coulomb's Law

Spherical Co-ordinate System

## The Attempt at a Solution

I have attached my attempt as a picture but now I am stuck, I don't know how I can express the distance (h )from the point to the differential element in terms of the other variables. From symmetry I know the y component of the electric field will cancel out
