Electric potential at midpoint of dipole

WebApr 3, 2024 · $\begingroup$ @adosar When the dipole is anti-parallel, the potential energy as a function of $\theta$ attains a local maximum instead of a local minimum. You can verify this by plotting $-\cos\theta$ versus $\theta$. This means that although the dipole will be in static equilibrium when exactly anti-parallel, that equilibrium will be unstable; any … WebApr 10, 2024 · No. Zero potential, at a given point in space, does not mean zero electric field at that point. The field is minus the gradient of the potential. So, at points on that …
