A small sphere of mass 2. 5 × 10–5 kg carries a total charge of 6. 0 × 10–8 c. The sphere hangs from a silk thread between two large parallel conducting plates. The excess charge on each plate is equal in magnitude, but opposite in sign. If the thread makes an angle of 30° with the positive plate as shown, what is the magnitude of the charge density on each plate?.
