    Depict the equipotential surfaces for a system of two identical positive point charges placed a distance 'd' apart.

    The figure shows equipotential surfaces due to two poit charges +3Q and -Q placed at a separation d. (a) Will the shape of epuipotential surface be spherical very close to both the point charges? What shape of equipotentials will be seen at very far away points from the pair of charges. (b) Find the distance of point P from the negative charge. (c) Find the potential of the surface marked as S_1 is the figure. (d) Consider the surface having zero potential. Write the flux of electric field through this surface

    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 a charge of 2 nC is taken from equipotential surface number 2 to 3, what is the amount of work done ?
