I have some problems withe this question:
Two positively charged particles A and B of masses of mA and mB respectively are suspended by two insulating threads of the same length from O. Due to the electrostatic repulsive force between A and B, threads from AO and BO make 30 degrees and 60 degrees respectively with the vertical as shown. Find the ratio mA:mB
I can find mA+mB but I can't find mA:mB
(the correct answer is 31/2 : 1)
