Which of the following is not the property of equipotential surfaces?
1 They do not cross each other
2 They are concentric spheres for uniform electric field
3 Rate of change of potential with distance on them is zero
4 They can be imaginary spheres
Explanation:
Any surface over which the electric potential is same everywhere is called an equipotential surface. The electric field and hence lines of force everywhere are at right angles to the equipotential surface. This is so, because there is no potential gradient along any direction parallel to the surface and so no electric field is parallel to the surface. This means the electric field and hence lines of force are always at right angles to the equipotential surface. Hence, they are not concentric spheres for uniform electric field. They are concentric spheres for an isolated point charge. Options (1), (3) and (4) are properties of equipotential surface.

The diagram below show regions of equipotentials :- A positive charge is moved from \(A\) to \(B\) in each diagram.
1 In all the four cases the work done is the same
2 Minimum work is required to move \(q\) in figure (a)
3 Maximum work is required to move \(q\) infigure (b)
4 Maximum work is required to move \(q\) in figure (c)
Explanation:
Work done on the charge is \(W = q\Delta V\) as \(\Delta V\) is same in all conditions, work will be same

Assertion : Surface of a symmetrical conductor can be treated as equipotential surface. Reason : Charges can easily flow in a conductor.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
In a symmetrical conductor, the charges distribute themselves in such a way that the electric potential is the same at all points on its surface, making it an equipotential surface. The reason is valid because charges shall easily move within a conductor to make \(\Delta V=0\) on surface So correct option is (1).

Nature of equipotential surface for a point charge is
1 Ellipsoid with charge at the centre
2 Sphere with charge at the centre
3 Sphere with charge on the sphere.
4 Plane with charge on the surface
Explanation:
