Reflection at a boundary of 2 media
Consider the boundary between media A and B. A single layer of a non-magnetic dielectric of refractive index n1, whose optical thickness is a quarter of a wavelength, is evaporated onto medium B. Show that the reflected and transmitted intensities of waves incident from medium A are now the same as if the medium B and the quarte ...continues
To determine the electric field at a point due to a system of charges.
Two point charges are fixed on the y-axis at the locations shown in the figure above (see attachment). A charge of +q is located at y = +a and a charge of +2q is located at y = -a. Express your answer to parts (a) and (b) in terms of q, a, and fundamental constants. a.) Determine the magnitude and direction of the electric f ...continues
Could you please explain this problem as I know only how to get polarisation of 2 single equal and opposite charges. Please do just the explanation about what needs to be done to solve this problem and leave the calculation up to me as in the problem I sent you before. The credit is 7 again but if you clock a slightly different ...continues

Could you please assist with the problem attached? Thank you.
the motion of a particle in uniform electric and magnetic fields
Full question is attached. 1) In this question we will consider the motion of a charged particle in uniform electric and magnetic fields that are perpendicular. You may ignore the effects of gravity throughout this question. a) i) Consider a charged particle of mass m and charge q which is moving in a uniform electric field ...continues
Inductance, energy and amplitude of induced current on an inductor consisting of 500 turns.
An inductor consists of 500 turns of wire of resistance 6.0 Ω wound tightly and uniformly on a toroidal ring of an insulating magnetic material with relative permeability μ = 40. The material is linear so μ is independent of the magnetic field. The mean radius of the toroid is 15 cm and the cross sectional area is ...continues
A capacitor consists of two concentric long cylindrical conductors of radii a and c, where c > a, and each is of negligible thickness. The space between the conductors is filled with two layers of dielectric materials. Using cylindrical co-ordinates with z-axis along the axis of the cylindrical conductors, the space a
Force on moving charge, charge density free electron density.
The full question is attached and comes in two parts, the first requires me to find the magnetic force acting on a point charge the second asks me to determine the charge density and current density of the current electrons in the wire as well as the residual positive charge in the wire? Please help and show you working.
