Problem 8: A parallel plate capacitor has a surface charge density of 0' = 1.2 sz on the le plate, which is parallel to the yaxis as shown in the gure. A sphere of charge Q is y placed between the plates and released. Acharya, 3m, sxaGOO3@mavs.uta.edu + + + + + + + x r :lhcnpcrltamum Part (a) Input an expression for the electric eld vector within the capacitor, E, using the unit vectors Land j.
