if i understand the question correctly... the sphere is floating so like one force acts upwards and one acts downwards. If it is floating, what does that say about the magnitudes of the electric and gravitational forces?

I'm not sure if what you did is right, but if I understand the problem correctly, you just need to do one calculation...
