WebJun 8, 2024 · then the density would be d q = σ d A = σ r d r d θ where θ is the polar angle on the disk since d A = r d r d θ is the area of a small piece of your disk, with radius r and arclength r d θ. For a point located on the z ^ axis at Z ≠ 0, this small amount of charge will produce the infinitesimal field. d E → = d q 4 π ϵ 0 Z z ^ − r ...
WebThe electric field strength due to a dipole, far away, is always proportional to the dipole moment and inversely proportional to the cube of the distance. Dipole moment is the product of the charge and distance between the two charges. Let's derive the expression for this field on the axis of the dipole. Created by Mahesh Shenoy.
