## What affects the strength of an electrical field?

The electric field strength is dependent upon the quantity of charge on the source charge (Q) and the distance of separation (d) from the source charge.

Where is the electric field the strongest?

Field-Line Patterns The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest. If the lines are uniformly-spaced and parallel, the field is uniform.

Why can’t two electric field lines cross?

Electric field lines cannot cross. If they did, they would be telling you that the force on a charge at that location would point in two different directions, which does not make any sense at all. Equipotential lines at different potentials can never cross either.

### Are electric field lines straight?

Electric field lines never intersect. In an uniform electric field, the field lines are straight, parallel and uniformly spaced. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential.

Can electric field be negative?

Electric Field can never be negative . As electric field is Force experienced by charge divided by magnitude of charge . Hence Electric Field also becomes positive . So , electric field is always positive .

Is it possible to cross electric field lines?

Electric field lines never cross each other. Electric field lines are most dense around objects with the greatest amount of charge. At locations where electric field lines meet the surface of an object, the lines are perpendicular to the surface.

## What is the formula for electric field?

the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation E = kQ/r2, where k is a constant with a value of 8.99 x 109 N m2/C2.

Why can’t magnetic field lines cross?

Magnetic field lines can never cross, meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

Can electric field lines intersect in free space?

Every single location in space has its own electric field strength and direction associated with it. Consequently, the lines representing the field cannot cross each other at any given location in space.

### What are the factors that help determine the strength or weakness of an electric field?

Name the two factors that affect the strength of electric force, and explain how they affect it. The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges.

Can electric field lines form closed loops?

The electrostatic field lines do not form closed loop because no electric field line exist inside the charged body.

Which best describes the electric field created by a positive charge?

Which best describes the electric field created by a positive charge? Its rays point toward the charge. Its rays point away from the charge.

## What must exist for electric charges to flow?

To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The flow of electricity can be likened to a flow of water through a pipe.

Which statement is true for electric field lines?

Electric field lines can never Electric field lines point may from positive charges and toward negative charges. Electric field lines are continuous; they do not have a beginning or an ending. At every point in space, the electric field vector at that point is tangent to the electric field through that point.

What factors affect the electric force between two objects?

In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

### What factors affect how strong the electric field is between two charged objects?

Charles Coulomb determined how to figure out the strength of the force between charged particles. As we’ll discuss in this lesson, he found that the force between charged particles was dependent on only two factors: the distance between the particles and the amount of electric charge that they carried.

Which change increases the electric force between objects?

How does increasing the distance between charged objects affect the electric force between them? The electric force increases because the amount of charge has a direct relationship to the force. Which change increases the electric force between objects? Electrons are added to two negatively charged objects.
