# Your question: Does the electric field depend on the value of the test charge?

Contents

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.

## Why does electric field not depend on the test charge what does it depends on?

(The distance from the charged particle, nature of the charges causing the field, the magnitude of the charges causing the field) Its not depend on the nature of charges causing the field according to furmula of electric field magnitude is depend on the charges, distance between them,mediem of space.

## Does electric field change with charge?

The space surrounding a charged object is affected by the presence of the charge; an electric field is established in that space. A charged object creates an electric field – an alteration of the space or field in the region that surrounds it. Other charges in that field would feel the unusual alteration of the space.

## Does electric field E due to the source charge q depend upon test charge q?

The electric field is thus seen to depend only on the charge Q and the distance r; it is completely independent of the test charge q.

## Is electric field dependent on nature of charge?

<br> Reason: The electric field is independent of the nature of charge. … Electric field at the nearby point will be resultant of existing field and field due to the charge brought. It may increase or decrease if the charge is positive or negative depending on the position of the point with respect to the charge brought.

## What does 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.

## Does the force depend on the value of the test charge explain your answer does the electric field depend on the value of the test charge explain your answer?

The force is entirely dependent on the test charge! … The electric field is defined to be the force on a test charge divided by the value of the test charge, E = F/q. For a single charge like the one at the center of the animation, F = (kQq)/r2, so the electric field becomes E = kQ/r2.

## How do charges move in an electric field?

A positive charge placed in an electric field will tend to move in the direction of the electric field lines and a negative charge will tend to move opposite to the direction of the electric field lines.

## How distance of a test charge is related with electric field?

The strength of an electric field as created by source charge Q is inversely related to square of the distance from the source. This is known as an inverse square law. Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases.

## Why does a charge produce electric field?

Originally Answered: Why do charges create an electric field? Because when certain amount of energy is given to the charges, they started motion and transfer their energy to other particles and this movement of charges produces electricity.

## What is the difference between Q and Q in physics?

In this case, the charges are Q and q. Big Q represents the source charge which creates the electric field. Little q represents the test charge which is used to measure the strength of the electric field at a given location surrounding the source charge.

## What is the difference between Q and E in physics?

q is the symbol used to represent charge, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 1019 Coulombs.

## How do electric forces and fields affect electric charges?

Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

## Why do electric field lines point away from positive charges?

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.

## What is the electric field of a point charge?

The electric field of a point charge is, like any electric field, a vector field that represents the effect that the point charge has on other charges around it. … If the charge is positive, field lines point radially away from it; if the charge is negative, field lines point radially towards it.

## What is test charge and source charge?

A test charge is a vanishingly small positive charge that is used to detect the presence of an electric field. The test charge should be as small as possible so that its presence does not affect the electric field due to the source charge. The electric charge that produces the electric field is called a source charge.
