Question

Which of the following is correct for the case of an uniform electric field?
A) All points are at the same potential
B) No two points can have the same potential
C) Pairs of points separated by the same distance must have the same difference in potential
D) None of the above

Answer 1

We need to find out the correct option which is true for uniform Electric Field. For that first of all we need to know the properties of the uniform electric field. After that we need to compare it with the given options and then finally conclude with the correct answer.

Complete answer:
First of all we need to go through the properties of uniform Electric fields.
The properties are as follows:
1. The field lines never intersect each other.
2. The field lines are perpendicular to the surface of the charge.
3. The magnitude of charge and the number of field lines, both are proportional to each other.
4. The start point of the field lines is at the positive charge and end at the negative charge.
5. For the field lines to either start or end at infinity, a single charge must be used.
6. The field is stronger when the lines are close together, and it is weaker when the field lines move apart from each other.
Now, we need to compare the given options with the properties of the uniform electric field.
We find that none of the properties matches with the properties indicated in the option.

Hence, option (D), i.e. none of the above is the correct choice.

Note: We should always be clear with the properties of the uniform electric field. Also we should have a clear concept about its formation and the condition for its formation. Electric field lines are a way of representing Electric fields. The region around the electric charge, in which the stress or electric force acts, is called an electric field. Also, when the electric field is constant at every point, then the field is said to be a uniform electric field.
