A dipole is a distance \(r\) from an infinitely-long line of negative charge of density \(\lambda\). The dipole moment \(\overrightarrow p\) is parallel to the line of charge. Find the magnitude of the torque on the dipole in terms of \(r\), \(\overrightarrow p\), and \(\lambda\).
16 Απρ 2023 · Electric dipole can be characterized by its dipole moment, which is a measure of the separation of positive and negative electrical charges within a system. Two point charges, one with charge +q and the other one with charge −q separated by a distance d, constitute an electric dipole.
18 Απρ 2024 · Definition. We know well how to deal with single point charges and an infinite charged plan which generates a simple form of an electric field, but of course physical systems rarely behave in such a simple way. What we are going to look at here is a model for two point charges that are equal in magnitude and opposite in sign. The reason this is ...
Describe a permanent dipole; Describe an induced dipole; Define and calculate an electric dipole moment; Explain the physical meaning of the dipole moment
Define and calculate an electric dipole moment. Explain the physical meaning of the dipole moment. Earlier we discussed, and calculated, the electric field of a dipole: two equal and opposite charges that are “close” to each other.
The electric dipole moment for a pair of opposite charges of magnitude q is defined as the magnitude of the charge times the distance between them and the defined direction is toward the positive charge. It is a useful concept in atoms and molecules where the effects of charge separation are measurable, but the distances between the charges are ...
