The potential energy (U) of an electric dipole in an electric field is given by the formula:U=−→P⋅→E=−PEcos(θ)Where:- P=10−6C-m (dipole moment)- E=102V/m=100V/m (electric field)- θ=60∘ Substituting the values:U=−(10−6C-m)⋅(100V/m)⋅cos(60∘)...

In particular, we analyze the zero modes analytically in various limits, both on ${\mathbf{R}}^{4}$ and on the four-torus, in order to compare with recent lattice QCD results, and study the implications for the electric dipole moment. 展开 ...
Appendix 1.4.A1 Dipole Moment A Dipole Consists of Two Equal Charges Separated by a Distance, d, and Is Described by its Electric Dipole Moment This appendix defines the dipole moment and derives an expression for its magnitude as a function of distance and angle from the center of the dipol...
We experimentally determine the conjecture that hydrogen-like atoms such as Rb and Cs may have large permanent electric dipole moments (EDMs). The saturated Rb vapour fills a cylindrical capacitor in the experiment. The influence of the vapour dielectric medium on capacitance is measured with a dig...
A bond-bond coupling dipole model is discussed for the absorption of the local-mode vibrations of XY 4 (Y = H, D). In this model the interaction between individual bonds is considered and cross terms occur in the dipole moment. The general forms of the coupling parameters α ii , β ij...
An electric dipole with dipole moment is placed near a large plane sheet with a surface charge density . If makes an angle of with the normal of the sheet, the magnitudeof the torque exerted on the dipole is . A、0 B、 C、 D、
In the scientific literature in the last 40 years, some data for the permanent dipole moment and the electric polarizability of Escherichia coli can be found [S.P. Stoylov, Colloid Electro-Optics – Theory, Techniques and Application, Academic Press, London, 1991]. In this paper the data bas...
