# Can the electric field at a point be zero?

## Can the electric field at a point be zero?

Yes, electric potential can be zero at a point even when the electric field is not zero at that point. At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential is zero.

What is the shape of equipotential surface for a uniform electric field?

A electric field lines are always perpendicular to equipotential surfaces. Was this answer helpful?

### What is the shape for the equipotential surface of a point charge?

The shape of the equipotential surface is in the form of concentric spherical shells. There is a decrease in the electric field as we move away from the point charge.

Why there is no work done in moving a charge from one point to another on an equipotential surface?

Answer. Answer: An equipotential surface is one in which all the points are at the same electric potential. If a charge is to be moved between any two points (say from point A to point B) on an equipotential surface, according to the formula dW=q‹…dVdW=q‹…dV, the work done becomes zero.

## Is equipotential surface real or imaginary?

Equipotential Surface A real or imaginary surface in an electric field which has same potential at very point is an equipotential surface or simply, an equipotential. Ex:- A shell having electric charge at its centre, makes an equipotential surface as it has same potential R Q 0 4 ïƒŽ ï at every point of the surface.

What is the example of equipotential surface?

a surface all of whose points have the same potential. For example, the surface of a conductor in electrostatics is an equipotential surface. In a force field the lines of force are normal, or perpendicular, to an equipotential surface.

### Why are there no directions indicated on equipotential lines?

Directions of the fields are indicated on field lines. Why are no directions indicated on equipotential lines? Since the rate of change of potential is zero along equipotential lines, the electric field is zero and there is no Direction.

How much work does it take to move a charge along an equipotential line?

The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines. Work is needed to move a charge from one equipotential line to another. Equipotential lines are perpendicular to electric field lines in every case. W = ˆ’Î”PE = ˆ’qÎ”V = 0.
