Draw an equipotential surface of two identical positive charges for small distance.

(N/A) When two identical positive charges are placed at a small distance from each other,they repel each other. The electric field lines originate from the positive charges and move outwards.
An equipotential surface is a surface where the electric potential is constant at all points.
For two identical positive charges,the equipotential surfaces are not spherical. Near each charge,the surfaces are nearly spherical,but as we move towards the region between the charges,the surfaces distort and merge.
In the region between the two charges,the electric field is weak (the neutral point exists at the midpoint),causing the equipotential surfaces to bulge outwards and eventually form a single surface enclosing both charges at larger distances.
