Homework Statement Two infinite coaxial metal cylindrical tubes of radius a and b (a < b) are charged with charge per unit length (unit [C/m]) \lambda and -\lambda respectively. Calculate the electric field between the tubes (i.e. for a < r < b) Where \epsilon_{0} is the permittivity...

Homework Statement A gas of electrons is contrained to lie on a two-dimensional surface. I.e. they have no movement in the z direction but may move freely in the x and y. a) From the equipartition theorem what is the expected average kinetic energy as a function of T? b) For T = 293K...
