《物理电学》英文版教学课件Electric Field of a Dipole.ppt,An electric dipole consists of two charges of the same magnitude q, but opposite sign, separated by a distance L. If the dipole is molecular, it could be an induced dipole created by external charg
The equation for the electric field of a dipole is E = k(q/r^3)(2cosθ), where k is the Coulomb constant, q is the magnitude of the charge, r is the distance between the charges, and θ is the angle between the line connecting the charges and the point in space where the ele...
A simple stand-alone scanning tunnelling microscope (STM) has been designed and constructed. It employs a spring-diaphragm assembly for a coarse approach and a concentric tube assembly as the scanner. It is functionally capable of STM operation (constant current, constant height, line test) and ...
Homework Statement The force exerted by a uniform electric field on a dipole is: A) Parallel to the dipole moment. B) Perpendicular to the dipole moment...
