Module 2 : Electrostatics

Lecture 9 : Electrostatic Potential

Recap
In this lecture you have learnt the following
	An electric dipole consist of a pair of equal and opposite charges separated by a small distance. The dipole
	moment is a vector whose magnitude is equal to product of the charge with the distance and has a direction from
	the negative charge to the positive charge.
	At large distances, the electric field due to an electric dipole varies as the inverse cube of distance from the dipole.
	A dipole does not experience a force in a uniform electric field. However, it experiences a torque in such a field. In
	an inhomogeneous field, the dipole experiences a force.
	The potential energy of a dipole in an electric field was calculated. The method was extended to compute the
	potential energy of a general charge distribution. Expressions for both discrete and continuous charge distribution
	were obtained.
	Congratulations! you have finished Lecture-9. To view the next Lecture select it from the left hand side of the page.
