# Do electric field lines have to be straight?

Contents

Electric field lines never intersect. In an uniform electric field, the field lines are straight, parallel and uniformly spaced. … If the electric field in a given region of space is zero, electric field lines do not exist. The tangent to a line at any point gives the direction of the electric field at the point.

## Do field vectors have to be straight?

It does not. It merely represent an idea of magnitude. So it wouldn’t make any sense to draw a single vector as a curved line. Even when drawing vector fields it is understood that at any given point the vector has a particular magnitude.

## Can uniform electric field lines be curved?

This means that the overlapping curved field lines will average out as a straight field line, through the middle of the point-charge pairs. The outermost edges of the electric field, on the other hand, will have nothing to interfere with, and remain curved.

## Why electric field lines are curved at the edges?

Not force values, but what you multiply its charge by to get the force values. Keep in mind that electric field lines represent a vector field and not a path, at those points on the edge of the plates the combination of all the forces exerted by the plate make a curved shape.

## Can electric field lines cross?

Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

## Can vectors not be straight?

Vectors in the plane or in space are not lines; they are straight-line motions. You can add two motions to get a third, or scale a motion to get a larger or smaller motion in the same direction. But they do not have a start or an end point the way a line segment does.

## Do field lines exist?

No, they do not exist. Electric field lines are only imaginary. They are the paths along which an imaginary unit charge would move when free. Their number is infinite as paths (Electric field lines) can be infinite.

## Where is the electric field the largest?

Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.

## Why are electric field lines not closed curves?

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.

## At which point 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.

## Under what condition the electric lines of force are curved?

Electric lines of force are straight line when there is single charge. If two electric charges are placed near each othe, the electric lines of force in between them becomes curved slightly.

## Can electric field lines form closed loops?

Since electric field lines originate and terminate on charges of opposite polarity, electric field lines can never form closed loops as to form a closed loop, the electric field lines must originate and end at the same charge.

## Can electric field be negative?

Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
