Forum:Introductory Physics Homework Help What should be the electric field intensity inside a sphere If the force acting between two point charges were proportional to \frac{1}{r^ 3}, instead of \frac{1}{r^ 2}, what would be the electric field intensity and charge density inside a charge...
The interfacial electron transfer led to the generation of an electric field pointing from g-C3N4to MS2. The increased number of transferred electrons induced a stronger electric field. The strength of the electric field was calculated using equationE=P/(εSd).P,ε,andSwere dipole moment, diele...

Boardworks Ltd 2015 Placing a charge in an electric field Electric field strength Electric field strength is defined as the force experienced per unit charge. The charge in the equation refers to the charge of the particle in the field. electric field strength = force / charge E = F / Q ...
The equation of state (EOS) and the axial ratio c/a of ∈-Fe at high pressures are investigated by using the generalized gradient approximation (GGA) within the plane-wave pseudopotential density functional theory (DFT). The results show that at the lower pressure, the EOS of ferromagnetic ∈...
integral equation forelectrons/motion in one-dimensional square wellThis paper presents an integral equation appropriate to a particle bound by an attractive force when a uniform electric field is applied. Two types of states arise corresponding to the homogeneous and inhomogeneous integral equations, ...
Equation (1) indicates that the electric wind is generated in the non-neutral region where \(n_{\mathrm{i}} \ne n_{\mathrm{e}}\). In the case of a cathode-directed (positive) streamer (that is a plasma bullet or pulsed plasma streamer) propagation, the electric wind is induced as...
