Sub Topic Name : For Points On The Axis |
|
Introduction
There exists a electric field, for a dipole at every point around the dipole, this topic tells us the field when the point is on the dipole axis.
Pre-Requisites:
Basic knowledge of Electric Dipole
Activity:
Find the direction of the field at any point at the dipole axis.
Real Life Question:
Why it is easier to calculate the field at the point on dipole axis rather than at any position?

| Different molecules | In chemistry, molecules uses this concept of electric dipole. |
What you learn in Theory:
Field on the dipole axis varies inversely with r3. Therefor for the condition r>>>a. field calculation is very simple.
What you learn in Practice:
It is easier to find out the electric field when the point is on the dipole axis.
