MCQ
. A surface that has the same electrostatic potential at every point on it is known as _____________.
  • A
    Equal-potential surface
  • B
    Same potential surface
  • C
    Equi-magnitude surface
  • D
    Equipotential surface

Answer

  1. Equipotential surface

Explanation:

Equipotential surface is a surface formed by the locus of all the points which are at the same potential. Equipotential surfaces do not intersect with each other and are closely spaced in the region of strong electric fields and vice-versa.
