What is the potential energy of a dipole placed in uniform electric field?

Let us consider an electric dipole of the dipole moment →P in a uniform electric field →E with →P making an angle θ with →E. , since the dipole axis is perpendicular to the field so potential energy is equivalent to zero.

What is the potential energy of an electric dipole placed parallel to an electric field?

Explanation: Consider a dipole with charges q1 = +q and q2 = -q placed in a uniform electric field as shown in the figure above. From the above equation, we can see that the potential energy of dipole placed in an external field is zero when the angle Ɵ is equal to 90° or when the dipole makes an angle of 90°.

What is the potential energy of a dipole when it is perpendicular to a electric field?

When finding the potential energy of a dipole in a uniform electric field, I was told by my lecturer that the convention is that the potential energy is 0 when the dipole moment and electric field vectors are perpendicular.

What is the potential energy of an electric dipole of moment p when it is perpendicular to an electric field E?

the potential energy of an electric dipole of moment P in the position perpendicular to electric field is taken zero.

What do you mean by potential energy of electric dipole?

Electric potential energy of an Electric dipole in dipole from zero energy position to the desired position (The zero enrgy position to be one when the dipole When an electric dipole of dipole moment p is on it such that P= P​× E​ W is the work done in turning the dipole from 0otoθ then, W=∫0W​dW.

What is potential due to dipole?

A dipole is a pair of opposite charges with equal magnitudes separated by a distance, d. The electric potential due to a point charge q at a distance of r from that charge is given by, V = 14πε0 qr. Where ε0 is the permittivity of free space.

What is the potential energy of a dipole in an external electric field give a proper derivation with final formula?

The potential energy of a dipole in an external field τ = p × E.

What is potential energy of a dipole?

Potential energy of a dipole in an external fieldElectric potential energy of an Electric dipole in dipole from zero energy position to the desired position (The zero enrgy position to be one when the dipole When an electric dipole of dipole moment p is on it such that P = [ P ] × [ E ] This torque tends to rotate the …

What is the potential energy of dipole moment p?

Potential energy of dipole in electric field is U=−pE cosθ; where θ is the angle between electric field and dipole moment vector.

At what angle between P and E electric dipole of moment P placed in a uniform electric field E has minimum potential energy?

When the angle between P and E is 0, then the potential energy of an electric dipole is minimum i.e. (-PE).

When potential energy of dipole is maximum?

When the angle between the dipole moment and electric field is 180° then the potential energy of electric dipole is maximum.

How do you find the potential energy of a dipole?

P.E=−pEcosθ=−p⋅E. This is negative when θ is acute and positive when θ is obtuse. You should verify that the product of p and E does have the dimensions of energy.

What is the electric dipole moment of a dipole?

The electric dipole moment is 1.60×10−27 C.m; the field magnitude is 3.00×106 N/C. What is the change in the dipole’s potential energy?

What is the potential energy of dipole placed in an external field?

From the above equation, we can see that the potential energy of dipole placed in an external field is zero when the angle Ɵ is equal to 90° or when the dipole makes an angle of 90°. Considering the initial angle to be the angle at which the potential energy is zero, the potential energy of the system can be given as,

How do you change the orientation of an electric dipole?

An external agent has to do work to change the orientation of the electric dipole. This work is stored as potential energy in the electric field set up by the system (the dipole and the charges responsible for the electric field).

How do you find the Y-component of an electric dipole?

E = k q r2 E = k q r 2. The y-component of electric field due to the electric dipole is a zero vector, that is the y-component of one charge is equal in magnitude and opposite in direction to the y-component of another charge. The y-component of →E 1 E → 1 due to positive charge is Esinθ^j E sin. ⁡.
