Frequent question: Can electrostatic potential at a point be zero while electric field at that point is not zero justify that answer?

Is it possible to have a point where potential is zero but not electric field give two examples?

A good example is the case of a dipole, which is two charges of the same magnitude, but opposite sign, separated by some distance. At the midpoint between the charges, the electric potential due to the charges is zero, but the electric field due to the charges at that same point is non-zero.

Is the electrostatic potential necessarily zero at a point where the electric field strength is zero give an example to justify your answer?

Electrostatic Potential and Capacitance

Electric potential necessarily need not be 0 if the electric field at that point is zero. For instance, at a point mid-way between two equal and similar charges, the electric field strength is zero but the electric potential is not zero.

Is it possible that the potential at a point is zero while there is finite electric field intensity at that point give an example?

Yes,There can exist electric potential at a point where the electric field is zero. Example:Inside the hallow spherical charged conductor, electric field is zero but potential is not zero. Yes, it is possible that at a point electric field is zero but potential is non-zero.

Is potential zero if electric field is zero?

If the electric field is zero, then the potential has no gradient i.e.: the potential is equal across space. But potential is always measured relative to a baseline, so it can therefore be considered as zero.

Is it possible for the electric potential at a point to be 0 V and for the electric field at that point to be non zero explain?

Yes, electrostatic potential can be zero at a point where electric field is not zero. Consider two charges +Q and -Q separated by a distance d.

How is electric potential zero between two opposite charges but the electric field is non zero?

Since the charges have equal magnitude and the distance from each to the mid point is the same, the magnitude of the potential energy contributed by each charge is the same, but the signs are opposite, so the net potential energy should be zero.

Is a zero potential point necessarily has zero intensity?

If the intensity of the electric field be E and potential be V, then the relation between them is, E=dVdx So, if E=0 at any point, we have dVdx=0 or, V = constant, Thus, the potential has a constant value, not necessarily zero, around that point.

Is there any region where electric potential is constant and electric field is zero?

If the potential is constant, then the slope of the potential is zero, which means the electric field is zero. An extra charge added to an otherwise constant potential region will experience no electrical force.

What does it mean when electric potential is zero?

What zero potential means, roughly, is that the charges in your system have cancelled out. For example exactly half way (or otherwise equidistant from them) between two equal and oppositely charged point charges, potential is zero.

Where is the electric potential zero?

The electric potential from a single charge is defined to be zero an infinite distance from the charge, and the electric potential associated with two charges is also defined to be zero when the charges are infinitely far apart.
