What does it mean when the electric field is zero?

That means that along the line connecting the charges, the left charge contributes a rightward electric field, and the right charge contributes a leftward electric field. They are equidistant so they both have magnitude E=kqr2. Doing the vector addition gives you →E=kqr2(right)+kqr2(left)=0. .

Is it possible for an electric field to exist in empty space?

Yes, an electric field exists in empty space, according to Maxwell’s equations.

Does the electric field in a region zero means that the potential in the region is also zero explain?

1. (a) No, just because the electric field is zero at a particular point, it does not necessarily mean that the electric potential is zero at that point. At the midpoint between the charges, the electric field due to the charges is zero, but the electric potential due to the charges at that same point is non-zero.

Can a zero electric field exist?

7) Is it possible to have a zero electric field value between a negative and positive charge along the line joining the two charges? Yes, regardless of the magnitude of the two charges. C) No, a zero electric field cannot exist between the two charges.

Where is the electric field zero?

For unlike charges, the electric field is zero outside of the smaller magnitude charge. For like charges, the electric field will be zero closer to the smaller charge and will be along the line joining the two charges. For opposite charges of equal magnitude, there will not be any zero electric fields.

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 the electromagnetic field in space?

The mutual interaction of electric and magnetic fields produces an electromagnetic field, which is considered as having its own existence in space apart from the charges or currents (a stream of moving charges) with which it may be related.

Is it possible for an electric field to exist at some point in space at which there is no charge?

Q20 Is it possible for an electric field to exist at some point in space at which there is no charge? Yes, all we need to have is a charge somewhere in space that can exert a force on a positive test charge brought to that point in space.

Is electric potential 0 when the electric field is 0?

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.

When the electric field is zero is the electric potential zero?

Can electric field exist at a point in a region where electric field is zero give one example?

Yes. The electric field might be generated for example by two charges: +5C and −4C separated by 2 meters. There is a point in between them where the potential is 0 (the electric potential is also 0 in the infinite) but in that point the electric field vector is not null.

Is the electric field zero in a certain region of space?

However, zero electric field does imply the potential is constant in that region of space. If you then know the potential at any point (potential always needs a reference), the you know it throughout that region–it is the same everywhere. If the electric field is zero throughout a certain region of space, is the potential also zero in the region?

What is the electric potential at the point where electric fields are 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. Originally Answered: What will be the electric potential at the point where electric fields are zero?

Is the electric field inside a conductor always zero?

Thus if E=0 then V is a constant but not necessarily zero. No! Electric field is zero inside a conductor of any shape and possessing any amount of charge, but the potential in its bulk is equal to the potential at its surface.

What is the derivative value of electric field when electric field is zero?

Going by the formula of electric field we know that. E=dV/dr. Thus if we are considering the field to be zero then above relation becomes. dv/dr=0. Therefore a derivative value when equal to zero means that there is no change the dependent value with respect to other independent value.
