It turns out that the expression for the potential energy of an electric dipole in an external field is simplest if we choose the potential energy of the dipole to be zero when the angle it makes with electric field is 90°.
In which situation the potential energy of dipole is minimum?
The potential energy of the dipole is minimum when the dipole is parallel to the external electric field. Also, it is the maximum when the dipole is anti-parallel to the external electric field.
At what point is the electric potential due to an electric dipole maximum?
The potential energy at a point due to an electric dipole will be maximum and minimum when the angles between the axis of the dipole and the line joining the point to the dipole are respectively: 90∘ and 180∘
At what angle we will get position of zero energy for a electric dipole?
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 are the points at which electric potential of a dipole has maximum value and minimum value?
(i) At axial points, the electric potential of a diople has maximum positive or negative value. (ii) At equatorial points, the electric potential of a dipole is zero.
What is the angle of electric dipole moment?
Therefore, the angle between dipole moment and electric field is 180°.
At what angle between dipole moment and electric field electric dipole remains in stable equilibrium?
The dipole is in constant equilibrium if θ = 0. A dipole in stable equilibrium, when Electric filed and dipole moment are perpendicular to each other i.e. the angle between them is zero degrees and torque will be maximum.
Is electric potential on dipole axis maximum?
The electric potential will be maximum at the dipole axis. … The electric potential will be zero at the perpendicular axis of the dipole.
What is the potential at a point due to a positive charge of 100μc at a distance of 9m?
V = 10^5 V
Therefore, electric potential due to charge is 10^5 V.
What is the electric potential due to an electric dipole at an equatorial point?
Electric potential at any point in the equatorial plane of dipole is zero.
What is the potential energy at 90 degree?
potential energy is zero when electric dipole is making 90 degrees angle…
When dipole placed in electric potential energy of dipole is?
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 potential energy of a dipole?
