Quick Answer: How can an electric field be uniform?

Electric field is said to be uniform at a point if field in neighborhood of the point is same as at the point concerned. Otherwise, non-uniform. In a uniform field, electric field lines are parallel and equidistant to each other. An example is a pair of two plates, one at 0 V, other at +500 V.

What makes an electric field uniform?

A uniform electric field is a field in which the value of the field strength remains the same at all points. In a uniform electric field, as the field strength does not change and the field lines tend to be parallel and equidistant to each other. They are equally spaced.

Why is electric field non uniform?

On the other hand, if the electric field is nonuniform, the force on each of the two poles of the dipole is not equal; therefore, the net force is not equal to zero and there is movement of the particle.

What makes an electric field non uniform?

When magnitude and direction of electric intensity are not the same at all the points in the electric field, then it is called a non-uniform electric field.

Why is electric field uniform in parallel plates?

It is precisely because the field strength diminishes like 1/r^2 with distance from a point charge that when a charge is spread uniformly over parallel plates that have a large radius compared to their separation that the field strength over a fairly large part of the region between the plates is nearly uniform.

Where does a uniform electric field exist?

A uniform electric field consists of two conducting plates. These plates are oppositely charged, and infinitely wide. Obviously, infinitely wide conducting plates do not exist, so uniform electric fields do not exist.

Which of the following is uniform electric field?

Answer: c) Two parallel plates.

Are electric field lines uniform?

If the electric field lines intersect, then two tangents could be drawn at their point of intersection. Thus, the electric field intensity at the point will have two directions, which is absurd. … An electric field is said to be uniform, when it has the same magnitude and direction in a given region of space.

How do you find non uniform electric field?

For a non-uniform electric field, the electric flux dΦE through a small surface area dS is given by dΦE=E⋅dS d Φ E = E ⋅ d S (the electric field, E, multiplied by the component of area perpendicular to the field).
