# What two things does an electric field depend on?

Contents

TRUE The E vector depends upon two factors – the charge of the object creating the field and the separation distance from that charge. c. FALSE An object can be used to measure the strength of an electric field; such an object is called a test charge. The test charge encounters an electric force.

## What does the electric field depend on?

The strength of the electric field depends on the source charge, not on the test charge. … Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field.

## What are the two factors that affect an electric field?

Strength of an electric field is affected by the distance from the charge and the amount of charge that produces the field.

## What are the factors on which electric field at a point due to a point source charge depend?

Hence clearly the electric field depends on magnitude of charge, distance between the point charges and medium between the charge and the point.

## Why are electric fields important?

Electric fields (e-fields) are an important tool in understanding how electricity begins and continues to flow. Electric fields describe the pulling or pushing force in a space between charges. … The electric fields of single charges. A negative charge has an inward electric field because it attracts positive charges.

## What are the two things that determine the electromagnetic force between two objects?

The magnitude of the magnetic force between them depends on how much charge is in how much motion in each of the two objects and how far apart they are. The direction of the force depends on the relative directions of motion of the charge in each case.

## What are the quantities that electric field of a point charge depends?

The electrostatic field due to a point charge depends on the distance r and 1/r2.

## Which is stronger of the two electric field or magnetic field?

The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and the Lorentz force law. The force created by the electric field is much stronger than the force created by the magnetic field.

## What is electric field and electric field intensity?

What is Electric Field Intensity? The space around an electric charge in which its influence can be felt is known as the electric field. The electric field intensity at a point is the force experienced by a unit positive charge placed at that point. Electric Field Intensity is a vector quantity. It is denoted by ‘E’.

## What is the relation between electric field and force?

The electric field at a location indicates the force that would act on a unit positive test charge if placed at that location. The dimensions of electric field are newtons/coulomb, N/Cstart text, N, slash, C, end text. For a positive q, the electric field vector points in the same direction as the force vector.
