Topic Name : Electric Dipole |
|
Sub Topic Name : For Points On The Equatorial Plane |
|
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 equatorial plane passing through the center of the dipole.
Pre-Requisites:
Basic knowledge of Electric Dipole
Activity:
Find out the reason that why a charged comb attracts pieces of paper, in the terms of dipole moment.
Real Life Question:
Why it is easier to calculate the field at the point on the equatorial plane perpendicular to dipole axis rather than at any position?
Key Words / FlashCards

|---|---|
| Text book | You can learn about this more from the text book. |
Real life uses :
To determine the polarity and nature on any molecule.
Places to visit :
Physics as well as chemistry lab, also u can refer your chemistry text book.
Practical examples around us
| Examples | Explainations |
|---|---|
| Different molecules | In chemistry, molecules uses this concept of electric dipole. |
What you learn in Theory:
.Field on the equatorial plane perpendicular to 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 equatorial plane perpendicular to the dipole axis.
