Which of the following charges can form an electric dipole?

What are the type of charges in an electric dipole?

An electric dipole is a pair of equal and opposite charges separated by a considerably short distance. … Since an electric dipole is a pair of equal and opposite charges, therefore the total charge in an electric dipole will be zero.

What forms electric dipole?

Let the first charge be negative and the second charge is positive. This combination can be called an electric dipole. Therefore, we can say that an electric dipole is created by the combination of equal and opposite charges by a separation of a certain distance.

How do you find the electric dipole charge?

The formula for electric dipole moment for a pair of equal & opposite charges is p = qd, the magnitude of the charges multiplied by the distance between the two.

What is an electric dipole give two examples?

Dipole-dipole forces are the attraction between the positive end of one molecule and the negative end of another. Ammonia molecule (NH 3) is an example of electric dipole.In NH 3, the centre of mass of positive charge and centre of mass of negative charge are some distance apart hence resulting in a dipole.

Which material is having permanent electric dipole?

The water molecule, H2O is a good example of a molecule having a permanent dipole moment since the electrons from the hydrogen atoms spend more time near the oxygen atom then with the hydrogen atoms. This results in an effective and permanent charge separation.

What is electric dipole give example?

An electric dipole deals with the separation of the positive and negative charges found in any electromagnetic system. A simple example of this system is a pair of electric charges of equal magnitude but opposite sign separated by some typically small distance. (A permanent electric dipole is called an electret.)

What is called electric dipole moment?

The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system, that is, a measure of the system’s overall polarity.

What do you mean by an electric dipole and electric dipole moment?

An electric dipole is a separation of positive and negative charges. The electric dipole moment is the product of the magnitude of the charge and the distance between the centres of positive and negative charges.

How does a dipole behave in electric field?

In an electric field a dipole undergoes a torque, tending to rotate so that its axis becomes aligned with the direction of the electric field. … The electric dipole moment, a vector, is directed along the line from negative charge toward positive charge.

What is dipole in electric field?

A pair of electric charges with an equal magnitude but opposite charges separated by a distance d is known as an electric dipole. The electric dipole moment is a vector having a defined direction from the negative charge to the positive charge. …

What is dipole moment example?

A dipole moment is simply the measure of net polarity in a molecule. … Polar molecules exhibit a large difference in electrical charge (a positive end and a negative end), otherwise known as a dipole moment. For example, ammonia (NHsub3) is a polar molecule.

What is an ideal electric dipole?

An electric dipole is composed of two electric charges with opposite signs brought very close together. An ideal electric dipole is one in which the two charges are only infinitesimally separated.

Where is the electric field strongest in a dipole?

The pattern of the lines for the dipole indicates that the electric field is greatest in the region between and immediately surrounding the two charges, since the lines are closest together there.
