A small sphere with mass 1.30 g hangs by a thread between two large parallel vertical plates 5.

A small sphere with mass 1.30 g  hangs by a thread between two large parallel vertical plates 5.00 cm apart (see the attachment). The plates are insulating and have uniform surface charge densities +theta and -theta. The charge on the sphere is  q = 8.00×10^−6 C.
What potential difference between the plates will cause the thread to assume an angle of 30.0 degrees with the vertical?
