# What is the direction of electric field line at a point with respect to equipotential surface give reason?

Contents

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 direction of electric field at a point on an equipotential surface?

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.

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

Equipotential lines are always perpendicular to the electric field. In three dimensions, the lines form equipotential surfaces. Movement along an equipotential surface requires no work because such movement is always perpendicular to the electric field.

## What is the orientation of electric field vector to an equipotential surface?

The component of electric field parallel to an equipotential surface is zero, as the potential does not change in this direction. Thus, the electric field is perpendicular to the equipotential surface at each point of the surface.

## How do the electric field line oriented with respect to equipotential surface?

Equipotential lines are always perpendicular to the electric field. In three dimensions, the lines form equipotential surfaces. Movement along an equipotential surface requires no work because such movement is always perpendicular to the electric field.

## What is the general relation between electric field and potential?

The relationship between potential and field (E) is a differential: electric field is the gradient of potential (V) in the x direction. This can be represented as: Ex=−dVdx E x = − dV dx . Thus, as the test charge is moved in the x direction, the rate of the its change in potential is the value of the electric field.

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

Electric field lines begin on positive charges and radiate away from them toward negative charges, where they terminate. 3. Equipotential lines are lines connecting points of the same electric potential. All electric field lines cross all equipotential lines perpendicularly.

## Can two equipotential lines cross?

Equipotential lines at different potentials can never cross either. This is because they are, by definition, a line of constant potential. … If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

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

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

## Why electric field is always at right angles to 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.
