Introduction
A pair of charges, one positive and one negative makes the system of electric dipole.
Pre-Requisites:
Knowledge about and basic electric field and electric field lines.
Activity:
Find out the pattern of electric field lines in an electric dipole.
Real Life Question:
Why the sum of electric field is 0 when two charges are at very much distance from each other?

What you learn in Theory:
Two opposite signed point charges separated by a distance 2a make an electric dipole.
What you learn in Practice:
Sum of charges in the electric dipole is zero, but the field may or may not be zero depending on the distance between two charges.
