Equipotential Surfaces
Question

Consider a particle with charge $$q=1.50 \times 10^{-8} \ C$$, and take $$V=0$$ at infinity.
(a) What are the shape and dimensions of an equipotential surface having a potential of $$30.0 \ V$$ due to $$q$$ alone?
(b) Are surfaces whose potentials differ by a constant amount ($$1.0 \ V$$, say) evenly spaced?

Q3
If we draw a surface in such a way that the electric potential is same at all the points of the surface, it is called equipotential surface. The component of electric field parallel to equipotential surface is zero. Mathematically we can say it is locus of points having same value of electric potential. Consider a situation where charge q is placed at the point (a, 0) and another charge aq(a < 0) is placed at point $$\left ( \dfrac{a}{\alpha}, 0 \right )$$
