Is it possible for an electric field at a point to be equal to zero?

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 potential due to the charges is zero, but the electric field due to the charges at that same point is non-zero.

Is it possible for the electric field between two positive charges?

Is it possible for the electric field between two positive charges to equal zero along the line joining the two charges? Yes, regardless of the magnitude of the two charges.

Can an electric potential exist at a point in?

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.

What is the relation between electric field intensity and electric potential?

The relation is very simple. Electric field intensity is equal to the negative of rate of change of potential with respet to the distance or it can be defined as the negative of the rate of derivative of potential difference, V with respect to r, E = – dV/dr.

Why electric field intensity is zero inside the conductor?

We know that electric field intensity is defined as the force per unit charge. The electric field intensity inside a charged conductor is zero because there are no electric lines of force within the conductor.

How do you find the electric field intensity between two charges?

The electric field intensity at a point is the force experienced by a unit positive charge placed at that point.

1. Electric Field Intensity is a vector quantity.
2. It is denoted by ‘E’.
3. Formula: Electric Field = F/q.
4. Unit of E is NC-1 or Vm-1.

Can electric potential be zero when the electric field is not zero?

Can electric potential be zero when the electric field is not zero?. Yes, electric potential can be zero at a point even when the electric field is not zero at that point. Considering the case of the electric dipole will help us understand this concept.

Can electric field intensity be zero at mid point of path?

It can be understood with the Case of Electric Dipole. Yes take an example. If we have a positive and a negative charge of equal magnitude separated by a certain distance , then the electric potential at the mid point of the path is 0 but the electric field intensity is non zero there.

What is the difference between electric potential and electric field intensity?

If we have a positive and a negative charge of equal magnitude separated by a certain distance , then the electric potential at the mid point of the path is 0 but the electric field intensity is non zero there. Remember electric potential is a scalar quantity but electric field intensity is a vector quantity.

What is the electric potential at the midpoint between two charges?

So there is the answer. The electric potential at the midpoint between the two +Q charges where the electric field is zero is nonzero and negative. The minus sign says that you have to do work to bring the positive test charge to the zero field point from infinity.
