Which of the following is not the property of equipotential surfaces?a...
For a uniform electric field, equipotential surfaces are concentric spheres is NOT the property of equipotential surfaces. In uniform electric field, equipotential surfaces are never concentric spheres but are planes ⊥ to Electric field lines.
So,
(i) Equipotential surfaces do not cross each other.
(ii) Equipotential surfaces are never concentric spheres but are planes ⊥to Electric field lines.
(iii) The rate of change of potential with distance on them is zero.
(iv) They can be imaginary spheres.
Hence, the Correct Answer is B

Equipotential surfaces
Equipotential surfaces refer to a set of points in space where the electric potential is the same. These surfaces are imaginary surfaces that are used to depict the distribution of electric potential in space. Some of the properties of the equipotential surfaces are as follows:
a) They do not cross each other: Equipotential surfaces are always perpendicular to the electric field lines. Since electric field lines do not cross each other, equipotential surfaces also do not cross each other.
b) They are not concentric spheres for uniform electric field: In a uniform electric field, equipotential surfaces are parallel planes, not concentric spheres.
c) Rate of change of potential with distance on them is zero: Since all points on an equipotential surface have the same potential, the rate of change of potential with distance on them is zero.
d) They can be imaginary spheres: Equipotential surfaces do not necessarily have to be physical surfaces. They can be imaginary surfaces that are used to represent the distribution of electric potential in space.
Explanation of the answer
Option B states that equipotential surfaces are concentric spheres for a uniform electric field. This statement is incorrect since equipotential surfaces in a uniform electric field are parallel planes, not concentric spheres. Therefore, option B is the correct answer.

They can be either spherical, cylindrical, planar sheets it depends on charge distribution and rate of change of potential with distance is electric field and it's not zero ,but it is constant hence option D
