A small sphere with mass 1.2 g hangs by a thread between two parallel vertical plates 5.00 cm apart. The plates are insulating and have uniform surface charge densities +σ and −σ. The charge on the sphere is q=9×10 −6 C. What potential difference between the plates will cause the thread to assume an angle of 37 ∘ with the vertical as shown in figure ?
