Since i already ansvered your planes i might do this aswell. General advice for all these, if you don't know what to do instantly draw a picture. Same cosine therom as in other one. Draw a picture into a triangle, have the starting point as origo and draw coordinate system...

F=(1/4pii*8.85419*10^-12F/m)*Q1Q2/r^2 Since the charges were same just opposite you can put Q1Q2 as Q^2. Solve Q. Then deduct from the ansver the charge there already is and divide by elementary charge.
