## Why do equipotential surfaces about a single charge in a constant electric field in z direction are not equidistant?

Equipotential surface in a constant field in Z- direction. ii) The equipotential surface about a single charge is not equidistant because V is inversely proportional to r. Also, the equipotential surfaces about a single charge are not equidistant because electric field due to a single charge is not constant.

## What is the difference between electric field and equipotential surface?

An equipotential line is a line along which the electric potential is constant. An equipotential surface is a three-dimensional version of equipotential lines. Equipotential lines are always perpendicular to electric field lines.

## What is the equipotential surface corresponding to a constant electric field in the Z direction?

Hence, the equipotential surfaces for a constant electric field in Z direction are planes parallel to the xy plane.

## What is the direction of electric field with respect to an equipotential surface?

The electric field is always perpendicular to an equipotential surface.

## Are these surfaces equidistant from each other why?

No, these surfaces are not equidistant from each other.

## Why the equipotential surfaces about a single charge are Notequidistant?

The equipotential surface is not at an equal distance because the electric field due to a charge is not constant. The electric field is inversely proportional to the square of the distance of the point from the charge and electric potential is inversely proportional to the distance of the point from the charge.

## Why are electric field lines perpendicular to surfaces?

this is because there is no potential gradient along any direction parallel to the surface , and so no electric field parallel to the surface. This means that the electric lines of force are always at right angle to the equipotential surface.

## What is the surface angle between electric field and equipotential surface?

The angle between the electric field and the equipotential surface is always 90. The equipotential surface is always perpendicular to the electric field.

## Why is angle between electric field and equipotential surface?

This is because the electric field is defined as the (negative) gradient of the electrostatic potential, which means that the only electric field is allowed at a point on an equipotential must be perpendicular to the equipotential surface, otherwise it would have a non-zero component along the surface.

## What will be the equipotential surfaces corresponding to?

The surfaces where the potential has a constant value are called equipotential surfaces. The potential in a direction perpendicular to the direction of field remains constant irrespective of the magnitude of the field. Hence, equipotential surface would correspond to planes parallel to x-y plane.

## What happens in a region of constant potential?

In a region of constant potential (V = constant) , E=-dVdr=0, i.e., electric field is zero. As E=0, there can be no charge inside the region.

## What will be the equi potential surfaces corresponding to a uniform grid consisting of long equally spaced parallel charged wires in a plane?

Describe schematically the equipotential surfaces corresponding to a uniform grid consisting of long equally spaced parallel charged wires in a plane. … Near the grid, the equipotential surfaces are of periodically varying shape which gradually reach the shape of planes parallel to the grid at a certain distance.
