1. The problem statement, all variables and given/known data Charge is distributed uniformly over the surface of a very large thin insulating plate to a density of 5.00 x 10–6 C/m2 . An insulating string connects a tiny charged bob to the vertical plate as shown in the diagram. If the mass of the object is .001 g and the string makes an angle of 30o to the plate, how much charge is carried by the bob? 2. Relevant equations I have no clue. 3. The attempt at a solution No idea where I should start. Can someone point me in the right direction?
