One final electric field problem

AI Thread Summary
The discussion revolves around calculating the electric field at point P, located on the axis of a charged ring. The ring has a radius of 0.029 m and a total charge of 1.35 x 10^-9 C. The user initially applies the formula E = (kQx) / (x^2 + a^2)^(3/2) but encounters issues with the results. It is suggested that the formula itself is correct, indicating that the problem may lie in arithmetic errors during calculations. The focus remains on verifying the application of the formula and ensuring accurate computation to determine the electric field at the specified point.

A ring-shaped conductor with radius a=.029 m has a total positive charge Q=1.35x10^-9 C uniformly distributed around it. The center of the ring is at the origin.
What is the electric field at point P, which is on the axis at x=.3m?
I used the equation E=(kQx)/(x^2+a^2)^3/2, but this doesn't seem to work.
Many thanks if you could help me!

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
