What is the electrical field when the distance goes to 0?

At what distance is the electric field 0?

Correct answer:

Therefore, the only point where the electric field is zero is at , or 1.34m.

What does it mean for electric field to be 0?

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.

When the electric field is zero at a point the potential?

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.

At which point or points is the electric field zero in?

1. The electric field is zero at two points along the x axis; one such point is to the right of the -2q charge and the other is to the left of the +4q charge.

In which regions electric field can be zero?

Thus the electric field between electron and proton will be zero in case I and III. Explanation: In case IV the electron is situated faraway from that point. So force due to electron can not be balanced by the force on proton.

Why electric field is zero inside a conductor?

A conductor is a material that has a large number of free electrons available for the passage of current. … Hence in order to minimize the repulsion between electrons, the electrons move to the surface of the conductor. Hence we can say that the net charge inside the conductor is zero.

Can electric field be zero when electric potential is not 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.

When the electric field becomes zero Which of the following relations hold good?

Explanation: The electric flux density of a field is the sum of εE and polarisation P. It gives D = εE + P. When electric field becomes zero, it is clear that D = P.

When the electric field is zero at a point the potential must also be zero there when the electric field is zero at a point the potential must also be zero there?

(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. A good example is the case of two identical charges, separated by some distance.

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.

Can the electric field be negative?

Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field.

Where would the net electric field be zero if one of the charges were negative?

(b) The net electric field between positive and negative charges would be zero only at an infinite distance aside from the electric dipole.
