1. The problem statement, all variables and given/known data Suppose that the magnitude of the charge on the yellow sphere is determined to be 2q. Calculate the charge q_red on the red sphere. Express your answer in terms of q , d_1 , d_2 , theta and . Hi Guys iv done the first two bits to this problem the sign of the charge on the yellow sphere is negative and the sign of the charge on the red sphere is positive. I cant do this third part though. It would be gr8 if you could help me out. I dont know where to start.
