Two isolated spherical conductors have radii 5 cm and 10 cm respectively. They have charges of $12 \mu C$ and $-3 \mu C$. Find the charges after they are connected by a conducting wire. Also find the common potential after redistribution.

$q_1^1=\bigg(\large\frac{1}{1+2}\bigg)$$(9)=3 \mu C q_e^1=\bigg(\large\frac{2}{1+2}\bigg)$$(9)=6 \mu C$
Common potential $5.4 \times 10^5 \;voltvolt$
