WebFeb 14, 2024 · Combing the two results above, we find that the total change in potential energy is: (11.6.4) Δ P E p = − ( q d) E cos θ. Note that the energy is a minimum when the dipole moment aligns with the external electric field. 11.6: Electric Dipole is shared under a not declared license and was authored, remixed, and/or curated by LibreTexts. WebFigure 1.4.4 – Torque on a Dipole. Multiplying the forces by the moment arms, and summing, we find that the magnitude of the torque on this dipole is: (1.4.2) τ = 2 [ q E d 2 sin θ] = q d E sin θ. The magnitude of the dipole moment appears in the equation, as does the strength of the electric field, and the sine of the angle between them.
Web$\begingroup$ @LalitTolani the charges are assumed to be constituted into a dipole “at some time”, and the energy released during that operation is ignored (we have to set a zero somewhere, and we set it for the 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 9, 2024 · Answer: For a given dipole moment viz: p = q x 2 a , when the charge q gets larger and larger, the distance between the two charges keeps on decreasing.One must note that the product on the R.H.S should be managed to make it equal to the L.H.S. In this way we obtain an ideal dipole. However, the size of an ideal dipole is negligible.
