Given that two spherical conductors of radii r1 and r2 are separated by(adsbygoogle = window.adsbygoogle || []).push({});

x>>(both r), connected by a thin wire, and charged with 7 uC - how is the charge distributed between the spheres (no charge on wire)?

I tried using charge density but:

Qtot/A1+A2 = Q1/A1 + Q/A2 doesn't work by definition

then maybe:

C(dV) = Q for either sphere - but how do you find dV without knowing the charge on each first? However, I got the correct answers when I flukily got dV by using the total charge of the system (7uC) and the sum of the radii (r1+r2) and multiplying by C of each sphere. I don't understand why this worked though.
