What does an electric field line represent?

Electric field lines reveal information about the direction (and the strength) of an electric field within a region of space. If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location.

Do charges follow electric field lines?

given a test charge at rest at a point in the region of the electric field the charge will continue to move along the path of the field line passing through that point.

Why do electric field lines come from positive charge?

Electric field line is supposed to be the trajectory of a “test charge” (a unit positive charge) in a given electric field. Since like charges repel each other, the test charge will move away from the positive charge, so the field lines move away from a positive charge.

Why do Charges move in an electric field?

As another charged object enters the space and moves deeper and deeper into the field, the effect of the field becomes more and more noticeable. Electric field is a vector quantity whose direction is defined as the direction that a positive test charge would be pushed when placed in the field.

Where do electric field lines from a positive charge go when there is no negative charge brought near for them to terminate?

Field lines should always point away from positive charges and towards negative charge.

Which of the following represents the electric field lines for a single positive charge?

radially outward
The field lines of a single positive charge are radially outward.

Which of the following electric field lines represent uniform electric field?

Uniform electric field is represented by parallel and equally spaced filed lines.

What path do Charges follow between the electrodes?

A line of force or electric field line is the path a charge would follow if it were allowed to move along in exactly the direction of the force acting on it. By convention, the sense of E is the direction of the force on a positive test charge.

What do electric field lines tell you about how the movement of charges is affected by the field?

The electric field will exert a force that accelerates the charged particle. The electric field has a direction, positive to negative. If a positive charge is moving in the same direction as the electric field vector the particle’s velocity will increase. If it is moving in the opposite direction it will decelerate.
