If vec(E ) equals zero at a given point mus V equal for that point .

On the basis of your understanding of the following paragraph and the related studied concepts. An equipotential surface is a surface with a constant value of electric potential at all points on the surface. The component of electric field parallel to an equipotential surface is zero, as the potential does not change in this direction. Thus, the electric field is perpendicular to the equipotential surface at each point of the surface. Further, say the direction of electric field electrical potential gradually fall with distance. If electric potential at origin point O be 100 V, then for electric field specified in part (b), draw equipotential surfaces corresponding to potentials 80 V, 60 V and 40 V respectively.

Draw equipotential surfaces around an isolated positive point charge + q. Mark direction of electric field vecE also.

4Statement - 1 : The electric potential and the electric field intensity at the centre of a square having four fixed point charges at their vertices as shown in figure are zero. Statement - 2 : If electric potential at a point is zero then the magnitude of electric field at that point must be zero.

ABC is a right anlged triangle situated in a uiform electric field vec(E ) which is in the plane of the traingle . The points A and B are at the same potential of 15 V while the point C is at a potential of 20 V. AB = 3cm and BC = 4 cm . The magnitude of electric field is (in S.I . Units )

STATEMENT-1 : At a point electrostatic field is zero, then potential at that point may be zero . and STATEMENT-2 : Negative of the potential gradient is equal to electrostatic field.

The electric field strenth vector is given by E= 2.5x hat I + 1.5y hat .The potential at point (2,2,1) is (considering potential at origin to be zero)
