Problem

Two isolated metallic solid spheres of radii

R

and

2R

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. (a)

\frac{5\sigma}{6}

(b)

\frac{5\sigma}{3}

(c)

\frac{7\sigma}{6}

(d)

\frac{7\sigma}{3}
