I believe B will also create a magnetic field perpendicular to the electric field. Here is my logic: * When there is an alternating electric field, charges will change position to keep up with the polarity which is same with the condition a. * As example: Assume you are charging a capacitor...

I believe Newton-Rhapsody iterative solving method might help you to find the roots if they are real ofcourse: http://en.wikipedia.org/wiki/Newton%27s_method

Well engineering wise, it is informative enough but specifically on control engineering it has not enough information.

In some level, it is correct. But I assume the question asks for a control block diagram. Please see http://en.wikibooks.org/wiki/Control_Systems/Block_Diagrams

I would advise to use a 2D low pass filter first to get rid of the noise as much as possible. In other means convolve the image with a gaussian matrix. Or in other saying take fft of the image and multiply with the fft of the gaussian matrix. And then take the inverse of the solution. Dimensions...

What do you mean by c? is it Coulomb? If yes, please see the definition of Coulomb from wikipedia: "One coulomb is the magnitude (absolute value) of electrical charge in 6.24150965(16)×1018 protons or electrons." http://en.wikipedia.org/wiki/Coulomb
