Electric potential difference is the work , done to bring a unit +ve test charge from one point to another in an electric field:- What Is the relation between electric field and electric potential ?

Electric potential difference is the work , done to bring a unit +ve test charge from one point to another in an electric field:- Can electric potential be necessarilly zero at a point where electric field strength is zero? Explain.

Electric potential difference is the work done to move a unit +ve test charge from one point to another in an electric field. Potential at a point Is given by the equation V = 3x^2+ 2y^2 + 4z^2 . Calcu-late the magnitude of field components at (2,1,1).

Electric potential at a point in an electric field is measured as the work done in bringing unit positive charge from infinity to that point:- The inetnsity of electric field at a point due to a point electric charge is 20NC^-1 and the electric potential at that point is 10 JC^-1 . Calculate the distance of the point from the charge.

E is the electric field intensity at any point in a uniform electric field. : What is meant by uniform electric field?

Mention any two difference between electric field and magnetic field.
