1. A small sphere of mass 2.5 x 10 kg carries a total charge of 6.0 x 10C. The sphere hangsfrom a silk thread between two large parallel conducting plates. The excess charge on each plateis equal in magnitude, but opposite in sign. If the thread makes an angle of 30° with the positiveplate as shown, what is the magnitude of the charge density on each plate? Note: for a parallelplate capacitor E =each plate).o/eo (electric field between plates and o is the surface charge density of30+.
