A small sphere with mass 1.50 g hangs by a thread between two parallel vertical plates 5.00 cm apart (Fig). The plates are insulating and have uniform surface charge densities +σ and - σ. The charge on the sphere is q = 8.90 X 10-6 C. What potential difference between the plates will cause the thread to assume an angle of 30.00 with the vertical?
