What is electric potential due to a dipole?
An electric potential is the amount of work needed to move a unit positive charge from a reference point to a specific point inside an electric field without producing acceleration. A dipole is a pair of opposite charges with equal magnitudes separated by a distance, d.
What is the formula of electric potential due to dipole?
Therefore, the electric potential due to an electric dipole at a given point is equal to KPcosθr2−a2cos2θ.
What is the formula of induced dipole moment?
Dipole Moment Formula A dipole moment is the product of the magnitude of the charge and the distance between the centers of the positive and negative charges. It is denoted by the Greek letter ‘µ’. It is measured in Debye units denoted by ‘D’. 1 D = 3.33564 × 10-30 C.m, where C is Coulomb and m denotes a metre.
When the electric potential due to a dipole is zero?
At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential is zero. Was this answer helpful?
What is the electric potential at the center of a dipole?
0
Answer 0. This is because the force exerted on the charge Q by the electric field between Q1 and Q2 is always perpendicular to the displacement of the charge in going from A to B. That means zero work is done.
What is induced dipole moment with example?
If a metal is placed in an electric field, the free electrons are attracted to one end of the metal, leaving an excess of positive charge at the other end. Thus a dipole moment is induced.
How is the induced dipole moment depends upon electric field?
Induced dipole moment depends upon the of the permanent dipole and the of the electrically neutral molecule.
Where is the electric potential zero?
The electric potential is zero at an infinite distance from the point charge. For two opposite charges of equal magnitude, the electric potential is zero in the middle since the electric field between both the charges will be equal and opposite.
What is electric potential due to a dipole in the end on position?
Thus the electric potential due to a dipole at any point on its broad side on (or transverse) position is zero (but the electric field intensity at this point is not zero).
Why potential is zero at center of dipole?
Since one is positive charge and the other is negative with equal magnitude, one of the energy is positive and the other is negative . If the charge is at equal distance from both charges ,the energy associated is zero .
What is an example of a dipole-induced dipole interaction?
Dipole-Induced Dipole Forces When an argon atom comes close to a polar HCl molecule, the electrons can shift to one side of the nucleus to produce a very small dipole moment that lasts for only an instant.
Which of the following interaction is dipole induced dipole?
The correct answer is (B) HCl and He Atoms. The forces or interactions, which occur between a polar molecule and a nonpolar molecule or with an atom are termed as Dipole -induced dipole interactions.
