Document Summary
Solution: the ux is h n ~eda, where n is directed out of the surface. For the right face this means that the normal is. Solution: the electric eld for a single charged plate has magnitude | |/(2 o). The eld goes away from the positively charged plate and towards the negatively charged plate. Thus, for this problem the electric elds of the two plates add constructively between the plates: | ~e| = (5 c + 7. 5 c)/(2 o 5 m2): a charged particle is held at the center of two concentric conducting spherical shells. A cross section is shown in the gure. If the charged particle at the center has charge. Solution: the electric eld inside the conducting shells is zero. Thus, the charge enclosed in a gaussian surface inside shell b is zero by gauss"s law. It is surrounded by a concentric charged cylindrical shell of radius.
