Question

Which of the following figure shows the correct equipotential surfaces of a system of two positive charges?

Answer 1

Answer:

Option (c) is the correct answer for the following question.

Explanation:

Equipotential surface is the surface on which at any point on it the potential remains same. For a point charge that equipotential surface comes out to a sphere along any radius r about that charge or keeping that charge as an origin. In c there are equally spaces circles around the positive charge.Hence we can say that those are equipotential surface for that charge. As each point on a circle will have the same potential. Also as the radius is increased the potential is decreased and taken to be 0 at infinity.
