Define electric field.

The electric field can be studied in terms of electric field intensity. a. What is an electric field? Define electric field strength. Given its unit and dimensional formula. c. Who introduced the concept of electric field? d. Is electric field a scalar quantity or a vector quantity?

Define an electric field.

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

In defining electric field due to a point charge, the test charge has to be vanishingly small. How this condition can be justified, when we know that charge less than the on an electron or a proton is not possible?

Define electric intensity at a point in an electric field.

Define potential at a point in an electric field.

Define potential at a point in an electric field.

Define electric dipole. Show that the electric field is the negative gradient of its potential.
