Two isolated metallic solid spheres of radii \( \mathrm{R} \) and \( 2 \mathrm{R} \) are charged such that both of these have same charge density \( \sigma \). The spheres are located far away from each other, and connected by a thin conducting wire. Then the new charge density on the bigger sphere is \( \frac{n}{6} \sigma \) then \( \mathrm{n} \) will be.
