30 мая 2016 г. · E=k*p/z^3. This is because usually, the Electric field is calculated at a point whose distance from the midpoint of the dipole(z) is very large ... |
29 мая 2014 г. · We have trivially (d⋅ˆr)=dcos(θ) where θ is the angle between d and ˆr (sign does not matter here). |
18 нояб. 2012 г. · For the dipole the electric field is locally constant, means that the positive charge and negative charge of the dipole feel the same electric ... |
15 мая 2015 г. · The electric field of a point charge drops off as an inverse square law, but that of a dipole varies as 1/r3. Why does the field drop off more ... |
30 янв. 2021 г. · The electric field due to this charge distribution at point (2x0,0,0) is given as →E(x)=nQπϵ0x20ˆx. The value of n (rounded off to three decimal ... |

12 июл. 2021 г. · It is possible to find Q and d separately if you have two measurements of E, and one measurement is close enough to the dipole. |
30 мая 2017 г. · The definition of the dipole moment of charge distribution ρ(x) is given by p=∫Vx′ρ(x′)d3x′. Start from the definition and all should be clear. |
