Explain axial field or electric field at a point in end-on position, i.e. the axial position of an electric dipole.
Step 1: To Find
Axial field or electric field at a point in end-on position.
Step 2: Calculate the axial field.
Let,
The charge of the electric dipole be and length be .
The electric field is at an axial point which is at a distance from the center of the dipole.
Where, (Dipole moment).
