, , , ,

So in the diagram showing a uniform electric field a positive charge would experience a downward force in the direction of decreasing electric potential. In this case the magnitude of the electric field is 205=4 N/C. If the

potential is constant

then the electric field is zero.

Is electric field zero in a region of constant potential?

In a region of constant potential (V = constant) ,

E=-dVdr=0

, i.e., electric field is zero. As E=0, there can be no charge inside the region.

When potential is zero What is electric field?

If the electric potential at a certain point is zero, then the

electric field at the same point

is also zero.

Can an electric field be zero?

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

.

What is the electric field in a region of constant potential?

In the region of constant electric potential,

electric field is zero

so there is no charge inside the region.

Under which condition electric intensity is zero but electric potential is not zero?

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.

Why electric field is normal to equipotential surface?

Since the electric field lines are directed radially away from the charge, hence they are opposite to the equipotential lines. … Therefore, the electric field is perpendicular to the equipotential surface.

Can electric field be negative?


An electric field can never be negative

. An electric field is a force experienced by the charge divided by the magnitude of the charge. … So even if the charge is negative in nature, its magnitude will also be positive and therefore, an electric field can never be negative.

Where is the electric field the strongest?

The field is strongest

where the lines are most closely spaced

. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.

Is it possible to have a zero electric field value between a negative and negative?

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.

Which of the following option is correct in a region of constant potential * The electric field is constant the field is infinite there is no electric field there can be a charge inside the region?

We know that charge produces electric fields. Since there is no electric field in the given region, we can say there are no any charges in the region. So, the correct answer is option

(B) and (C)

.

Is electric field at a point always continuous?

Option A-No,

the electric field is not always continuous

. … Note- The electric field because of any charge will be continuous, if there is no other charge in the medium. It will be discontinuous if there is a charge at that viable point.

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.

Can electric field be zero and 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.

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

(b) No, just because the electric potential is zero at a particular point, it does not necessarily mean that the electric field is zero at that point. A good example is the

case of a dipole

, which is two charges of the same magnitude, but opposite sign, separated by some distance.

Is electrostatic potential necessarily zero at a point where electric field strength is 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.
