Web13. júl 2024 · To get the correct form for the limit, change from the charge q to the electric dipole p = q d, to get F = p E ( r + d n) − E ( r) d. The true force on a point dipole is the limit of this as d → 0 , F = p lim d → 0 E ( r + d n) − E ( r) d, and this is exactly the directional derivative along n, typically denoted n ⋅ ∇, so F = p n ⋅ ∇ E = p ⋅ ∇ E. WebThe work done to rotate the dipole from θ = 0º to 90º is equal to the potential energy difference between these two configurations. W= ∆U =U (90º)−U (0º) From the equation (1.51), we write U = − pE cosθ, Next we calculate the work done to rotate one water molecule from θ = 0º to 90º. For one water molecule W = −pE cos 90º + pE cos0º = pE

Web3. apr 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 … Webthe dipole is concerned (Fig.2a). The interaction of our dipole with the other dipoles lying inside the cavity is, however, to be treated microscopically, which is necessary since the discrete nature of the medium very close to the dipoles should be taken into account. The local field, acting on the central dipole, is thus given by the sum
