Electric Dipole

Given: - Dipole consists of charges and separated by distance - Dipole moment in the direction from to Let us calculate the electric potential at a point at distance from the centre of dipole, where \underline{(I) Along the Axis:} The point lies along the axial line (line joining the two charges). Let the positive charge be at , and the negative charge at . Then the potential at point , at distance from centre, is: Using binomial expansion for : Since , we get: \underline{(II) Along the Bisector (Equatorial Line):} The point lies on the perpendicular bisector of the dipole. The distances from both charges are approximately equal: - Distance from each charge: (since ) - The potential at point due to both charges is: Therefore, % Final Answer Statement Answer:
- On the axial line:
- On the bisector (equatorial line):
