CHAPTER 1:Electrostatics

Objectives

* To get an idea about frictional electricity, charges and their properties
*To understand Coulomb's law and apply it to study the electric field due to a point charge and dipole
*To develop an idea about Electric field and to study the electric field due to a point charge and dipole.
*To understand the behavior of dipole in a uniform electric field.
*Tod develop an idea about electric potential ,potential difference and to study the electric potential due to a point charge, dipole and system of charges.
*To derive a mathematical expression for an electric potential energy of a system of point charges and electric dipole in an electric field.
* T understand Gauss's theorem and apply it to find electric field due to an infinitely long straight wire, uniformly charged infinite plane sheet and uniformly charged thin spherical shell.
