The equipotential lines round the infinitely long line of charge are concentric circles round the line of charge.

Equipotential line

An equipotential line is a line in which the electric potential is constant

  • Since the electric field of an infinitely long line of charge is perpendicular to the line of charge. At a given distance from the infinitely long line of charge, the electric field is constant. The electric field is constant within a circle round the line of charge. This circle round the line of charge is an equipotential line.

So, equipotential lines round the infinitely long line of charge are concentric circles round the line of charge.
