Electric Field Lines and Equipotentials

The Problem

Plot the electric field lines and equipotentials for two point charges q₁ and q₂ when (a) q₁ = q₂ = +q and (b) q₁ = +2q and q₂ = –q.

Physics of the Problem

Electric Field Lines

At position r, the electric field of a charge distribution consisting of a discrete distribution of N point charges q₁,q₂,..., q_N at positions r₁,r₂,..., r_N, respectively, and a continuous distribution of volume charge density ρ(r’) in the volume V and surface charge density σ(r’) on the surface S that bounds V is

Equation 5.1.1.

where ε₀ is the permittivity of free space. The electric field ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
