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 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 at a point in an electric field measured as the work done in bringing unit positive charge from infinity to that point:- Is electric potential a scalar or a vector quantity?

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.

Equipotentiai surface is a surface on which the electric potential is the same at every point:- A point charge +q Is placed at the centre of a sphere of radius B. An other point charge +q is take from a point A to another diametrically opposite point B on the surface of the sphere. Calculate the work done for this.
