A conducting sphere of radius r$1=0\mathrm{.}21$ m has a total charge of Q $=1\mathrm{.}9\backslash$mu C$.$ A second uncharged conducting sphere of radius r$2=0\mathrm{.}28$ m is then connected to the first by a thin conducting wire. The spheres are separated by a very large distance compared to their size.

Randomized Variables

r$1=0\mathrm{.}21$ m

r$2=0\mathrm{.}28$ m

Q $=1\mathrm{.}9\backslash$mu C

What is the total charge on sphere two, Q$2$ in coulombs?
