Homework Statement


x and y are nonconducting cylindrical shells. Both cylindrical shells are surrounding long wires that are carrying current. the x shell out of the page and the y shell into the page.
x radius has a charge per unit length = to +\lambda
y radius has a charge per unit length = to -\lambda
I need to calculate the maxwell stress tensor at a midway between x and y. (from the picture)

Homework Equations



Tij =\epsilono(EiEj-\deltaijE2)+(1/\mu)(BiBj-\deltaijB2)

The Attempt at a Solution



How do I exactly found the i and j component of the magnetic and electric field?

can anyone help me?
 
If you're studying the Maxwell stress tensor, you should already know how to calculate the electric and magnetic fields of simple charge distributions...surely you've already seen examples that include the magnetic field of a long straight current carrying wire and the electric field of a uniformly charged cylindrical shell?
 
i got the problem..thanks bye
