Define electric field

Define an electric field intensity. Is it a scalar or vector? What is its SI unit?

Define electric flux. Using Gauss's law derive an expression for electic field intensity due to uniformly charged infinite plane sheet.

Define electric flux. Give its SI unit. Using Gauss. law, deduce an expression for the electric field due to a uniformly charged spherical conducting shell of radius R at a point outside

Define electric flux. Give its SI unit. Using Gauss. law, deduce an expression for the electric field due to a uniformly charged spherical conducting shell of radius R at a point inside the shell

Define potential at a point in an electric field.

Define an electric dipole and mention the directions of electric field intensity.
