Uploaded: 2021-07-06T11:19:46Z
Description: Let's derive the expression for the torque acting on a dipole placed in a uniform electric field. We will also explore the stable and unstable equilibrium positions.

You when we tilt the dipole a little bit in 0°it tend to come back at same position but in unstable or 180° if we tilt dipole a little bit it tend to rotate to stable position so it's an unstable equilibrium

Shouldn't the maximum torque happens when positive e deviates a bit from the unstable equilibium?
