WebAnswer (1 of 6): The below derivation can be used to determine the electric field at any point due to an electric dipole. Thus this is a generalized expression and can be used to determine the electric field due to dipole at equatorial and axial point too. Consider a short electric dipole AB hav... Webelectric dipole moment is de ned as p= qa . By convention the vector apoints from the negative to the positive charge. Here we also take the origin to be at the centre and ato be aligned to the zaxis (see diagram) Figure 1: Diagram of electric dipole aligned along zaxis. Gri ths Fig 3.37 5. 1.
