Can anyone help me with a hint of some sort? I am lost...
A small sphere with mass 1.50 g hangs by a thread between two parallel vertical plates 5.00 cm apart. The plates are insulating and have uniform surface charge densities + and -. The charge on the sphere is q = 8.90 10-6 C. What potential difference between the plates will cause the thread to assume an angle of 30.0° with the vertical
