# Question: Can electric field lines cross each other?

Contents

## Why can’t two electric field lines cross each other?

Answer: Electric field does not direct in two directions that is why electric field lines never cross over each other. … When two lines intersect each other, tangents are drawn at that point indicating two directions of electric field lines, which is impossible therefore electric field lines cannot cross over each other.

## When can electric field lines cross?

Field lines can never cross. Since a field line represents the direction of the field at a given point, if two field lines crossed at some point, that would imply that the electric field was pointing in two different directions at a single point.

## What happens when two field lines cross each other?

The field lines never intersect each other. … The magnitude of charge and the number of field lines both are proportional to each other. The field lines’ start point is at the positive charge and the end at the negative charge. For the field lines to either start or end at infinity, a single charge must be used.

## Can electric field lines merge?

Two electric field lines can never intersect because electric field at a point is unique but can the 2 vectors add up to give a single vector.

## Why electric field lines do not pass through conductor?

The net electric field inside a conductor is zero. Therefore, the electric field lines do not pass through a conductor.

## Why do equipotential surfaces not intersect?

They cannot intersect each other because two different equipotential surfaces have different electric potential. … Now the electric field is always perpendicular to the equipotential surface. If they are not perpendicular there will be two components which can cause charge to move along the surface.

## What would crossed electric field lines indicate?

Electric field lines indicate the direction of the force due to the electric field on a positive test charge. Each electric force has its own direction at each point. If two electric field lines crossed, that would indicate that a force has two directions at the point at which they cross.

## Can electric field lines intersect in free space?

Question: Can electric field lines intersect in free space? Answer a. Yes, but only at the centroid of an equilateral triangle with like charges at each corner.

## What does it mean when the electric field lines are close together?

A line tangent to a field line indicates the direction of the electric field at that point. Where the field lines are close together, the electric field is stronger than where they are farther apart.

## Why do the electric field lines not form closed loops?

If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative. … Therefore, we say electrostatic field lines never form closed loops.

## What happens to field strength when two unlike equal charges overlap one another?

The field is stronger between the charges. In that region, the fields from each charge are in the same direction, and so their strengths add. The field of two unlike charges is weak at large distances, because the fields of the individual charges are in opposite directions and so their strengths subtract.
