Test: Equipotential Surfaces (NCERT) - Question 1

Consider a uniform electric field in the z-direction. The potential is a constant

Detailed Solution for Test: Equipotential Surfaces (NCERT) - Question 1

As the electric field in the z-direction is uniform, equipotential surfaces are in xy plane. Hence the potential for given z is constant on x-y plane, for any x in this plane and for any y in this plane. So all are correct.

Test: Equipotential Surfaces (NCERT) - Question 2

Equipotential surfaces

Detailed Solution for Test: Equipotential Surfaces (NCERT) - Question 2

Electric field,

i.e., equipotential surfaces are closer in regions of large electric fields compared to regions of lower electric field. At sharp edges of a conductor, charge density is more. Therefore electric field is stronger. Hence equipotential surfaces are more crowded.

Test: Equipotential Surfaces (NCERT) - Question 3

In a region of constant potential

Detailed Solution for Test: Equipotential Surfaces (NCERT) - Question 3

In a region of constant potential
 (∵ V = constant)
i.e., electric field is zero, so there can be no charge inside the region.

Test: Equipotential Surfaces (NCERT) - Question 4

Which of the following statements is true about the relation between electric field and potential?

Detailed Solution for Test: Equipotential Surfaces (NCERT) - Question 4

In the region of strong electric fields equipotential surfaces are close together and in the region of weak electric fields, equipotential surfaces are far apart.

Test: Equipotential Surfaces (NCERT) - Question 5

What is the angle between electric field and equipotential surface?

Detailed Solution for Test: Equipotential Surfaces (NCERT) - Question 5

Electric field is always perpendicular to the equipotential surface at any point.
