Q. A transmission line is constructed using strips of copper foil to construct a very long parallel plate capacitor. The length is L, the width is W and the plate separation is h. (L>>>W<<<h) A battery is connected to one end and a resistor is connected to the other end. This gives a surface current density K in the upper plate toward the resistor and returning to the battery in the lower plate. the potential difference produces a surface charge +σ on the upper plate and -σ on the lower plate.

a. use the maxwell stress tensor to find the pressure on the top plate.

b. what is the value of the R that gives zero pressure? write it in terms of h, W and fundamental constants
