Hello, dear scientists and forum users. I have recently finished programming the restricted closed-shell and unrestricted Hartree-Fock matrix equations. They seem to work fine for small diatomic molecules. However, I cannot understand the restricted open-shell theory that was firstly published...

Hello! I am studying Physics and Electronic and Communications Engineering double major. I really enjoy studying physics, and find it fascinating to manipulate difficult formulas that describe natural phenomena. However, I am concerned that there are far more engineering jobs out there than...

The current flows in the cylindrical surface, long rectangular plane, straight wire, or any other geometrical shapes that will give you circular loops of the magnetic field. Normally, the current is normal to a cross-sectional area at any time and it passes through the loops around which the...

The generalized forces can be both conservative and non-conservative. The gravitational force of attraction, the buoyancy force, the spring force, the electric and magnetic forces (and electromagnetic time invariant forces) are conservative and they also have the potential function associated...

Ampere's Law for finding magnetic fields in primarily useful when you deal with high-symmetry systems. Examples of these systems are: the magnetic field perpendicular to the direction of the current in a straight wire, the magnetic field of the thick cylindrical wire, having uniform charge...

The shell is an insulator, since there is a non-uniform volume charge density. If it was a conductor, there will be no charge inside the shell, and it will all be distributed on the inner and outer surfaces. Therefore, the integral gives the electric field inside the shell, as I have mentioned...

Homework Statement Lets say, there is a non-uniform charge distribution, given as in a spherical shell that has a cavity with radius a and the radius b to the outer surface. I am wondering if the field is discontinuous just on the surface of this sphere. Homework Equations...
