The angle between the electric field and the equipotential surface is always 900. The equipotential surface is always perpendicular to the electric field.

## What is the relationship between electric field lines and equipotential surfaces?

An equipotential surface is a three-dimensional version of equipotential lines. Equipotential lines are always perpendicular to electric field lines. The process by which a conductor can be fixed at zero volts by connecting it to the earth with a good conductor is called grounding.

## Why is the electric field always at right angles to the equipotential surface?

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 angle between electric field intensity?

Also the two are antiparallel, i.e., in opposite directions to each other. Hence, the angle between electric field strength and electric dipole moment is 180∘.

## What is the angle between the electric field vector and equipotential lines?

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

## What is the relation between the direction of electric field and equipotential line at the same point?

Equipotential surfaces have equal potentials everywhere on them. For stronger fields, equipotential surfaces are closer to each other! These equipotential surfaces are always perpendicular to the electric field direction, at every point.

## At what angle potential energy is zero?

When an dipole is placed in a uniform electric field with a angle of 90° or π/2, its potential energy is 0.

## What is negative gradient of electric potential?

While the magnitude of the electric field is equal to the gradient of the electric potential, the electric field points in the opposite direction of the gradient of the electric potential, and thus →E=−→∇V.

## What is meant by equipotential surface?

The surface which is the locus of all points which are at the same potential is known as the equipotential surface. … In other words, any surface with the same electric potential at every point is termed as an equipotential surface.

## What is the angle between electric field and electric dipole?

Therefore, the angle between dipole moment and electric field is 180°.

## What is the angle between the electric dipole?

The angle between electric dipole moment and electric field on the equatorial line is 180° as both of them are in opposite directions.

## What is the angle between the electric dipole moment and the electric field due to the dipole on its axial line?

The angle between the electric dipole moment and the electric field strength due to it on the axial line is.

## What is the angle between equipotential surface and lines of force?

The angle between equi-potential surface and lines of force is always 90 degree.

## What is the angle between the direction of electric field at an axial point?

The angle between the direction of electric field at any axial point and equatorial point due an electric dipole is 180∘.
