Since the rod is uniformly charged with q, the linear charge density of the rod is λ = ql. Consider a small length dr of the rod at a distance r from P. Charge of this portion of length dr, dq = λdr = qldr Electric field intensity at P due to this charge dq, dE = 14π...
The electric field at that point is going to be Coulomb’s constant multiplied by the charge generating the field, divided by the distance between the point charge and the test charge squared. This is equal to 9×109 Nm2/C2 times 1×10-8 C divided by (0.5m)2. Here we can cancel ou...
Torque on an Electric Dipole in a Uniform Electric Field Magnetic Dipole Moment Electric potential due to a Dipole (V) Suppose there are two charges, “–q”, placed at A, and “+q” placed at B, separated by a distance “d”, forming a dipole. Suppose the midpoint of AB is...
electric field due to a line of charge on axis We would be doing all the derivations without Gauss’s Law. At the same time we must be aware of the concept of charge density. Here since the charge is distributed over the line we will deal with linear charge density given by formula λ...
An analytical formula for the distance dependence of the electric field gradient produced by a Gaussian charge density distribution n ( r ) is derived. This charge density is displaced by z 0 along the z -axis. The system has cylindrical symmetry; hence it suffices to calculate V zz (0)....

We study the effect of finite electric field on the density of states (DOS) in a two-dimensional disordered system, extending our previous work about the magnetic field effect. Two cases are considered: (i) uniform electric field E and (ii) crossing fields E and H. The electric field supp...
