Homework Statement
I'm just trying to show that the equation in the attached image becomes E = Q/(2π ##ϵ_0## ##r^2##) * ##i^##, where ##i^## is i-hat, the unit vector for when r is the smallest that it could be, which is when r = d/2.
I'm doing this with reference to problem 1.2 (and I'm including problem 1.1 so that you have the background information for problem 1.2).
Homework Equations
The equation in the image as well as E = Q/(2π ##ϵ_0## ##r^2##) * ##i^##.
The Attempt at a Solution
My attempt is attached as MyAttempt.pdf.
Is it a coincidence that I'm getting double the value shown in problem 1.2?
Any help in getting to show that the vector equation for the electric field of a dipole breaks down to E = Q/(2π ##ϵ_0## ##r^2##) * ##i^## would be greatly appreciated!
