length3.21 cm. One sphere has a charge of-5.1 μCwhereas the other has a charge of +7.21μC. The sphere of charge-5.1μChas a fixed position while the other is free. The assembly is placed in an even external electric field of magnitude2.0 × 108N/C. What is the tension in the ...
Repetitive switching of magnetization in ferromagnetic materials is a key process in magnetic recording and information storage. Traditionally, this energy-intensive process is achieved by applying an external magnetic field or spin-polarized currents. An emerging alternative, however, is the use of an ...
A jellium/free-electron model is used to estimate the static electric field at the surface of a metal cluster. The electric field near a cluster with a radius of 10鈥 50 au is found to deviate significantly from the field at the same distance from an infinite metallic plane. This will ...

Consider a plane surface of area 50 mm2in a uniform electric field of magnitude 25 N/C. The angle between the electric field and the normal to the surface is φ. Determine the values of angle φ for which the electric flux magnitude through the surface is i) maximum or ii) minimum. ...
Here, we fix a process with an invariant field, and study the fluctuations of the flux through large arcs and curves in the plane. Under suitable conditions on the process and on the curve, denoted \Gamma , we show that the asymptotic variance of the flux through R\,\Gamma grows like ...
Electric potential is a scalar quantity that can be defined as the amount of work done in moving a unit positive charge (+1C) from one point to the other in an electric field. A charge q is present on a point object. The potential of the sphere at a distance r from it is giv...
