An object is placed in a uniform electric field. If the charge of the object is positive, which direction will it move? A. Against the direction of the electric field B. In a direction perpendicular to the electric field C. In the same direction as the electric field D. It will not ...
An electron is released from rest in a uniform electric field with a magnitude of \(5.0*10^{2} V/m\). What is the speed of the electron in \(m/s\) after being displaced a distance \(d = 0.8\,m\) in the opposite direction of \(\vec{E}\)?___ 相关知识点: 试题来源: 解...
The inventive method for forming a uniform electric field consists in supplying voltage to all phase rings during the passage of one of the alternating-current half-cycles from an electrode to an electrically conductive medium in such a way that the current is limited on each phase ring. The ...
The superposition of magnetic fields generated by each coil produces a highly uniform force field in the region between the coils. It means that at every point of that space, the magnetic field induction is constant. The schematic diagram of the magnetic field is presented in Fig. 4. Sign ...
An electric dipole with dipole moment is in a uniform electric field. If the dipole is in the stable equilibrium state,which of the following statements is correct?A.The torque is zero and potential energy is minimum.B.The torque is zero and potential en
device layout constraints and gatetunnelingcurrents (Razzak et al., 2020). To achieve high breakdown fields, these non-uniformities in electric fields force device layouts to include large separations between the drain and gate, and these large spacings invite AlGaN's high sheet resistance (Xue ...

Common practice suggest that a parallel two-electrode configuration may exhibit most uniform electric field. However, it is reminded that classic electrochemistry requires the counter electrode to be far larger (at least by one order of magnitude) than the working electrode. Simulation of such an el...
The direction of the force is perpendicular to both the particle velocity v (or current) and the magnetic field: F=qv×B. A charged particle moving on a plane perpendicular to a uniform magnetic field moves along a circle. The field concept was first stated by Michael Faraday. From years ...
(6.30), Jreci is uniform all over the tube and equal to 1/A, where A is the cross-sectional area of the tube. Integrating Eq. (6.30) H = zρ/A, where z is the unity vector in direction of the tube axis. From Eq. (6.30), the recorded voltage from the current dipole m is:...
