Two metal spheres, one of radius {\R} and the other of radius 2 {\R} respectively have the same surface charge density \sigma. They are brought in contact and separated. What will be the new surface charge densities on them? [NEET OD 2019]

Correct Answer is : σ1=53σ,σ2=56σ

\sigma_1=\frac{5}{6} \sigma, \sigma_2=\frac{5}{2} \sigma

\sigma_1=\frac{5}{2} \sigma, \sigma_2=\frac{5}{6} \sigma

\sigma_1=\frac{5}{2} \sigma, \sigma_2=\frac{5}{3} \sigma

\sigma_1=\frac{5}{3} \sigma, \sigma_2=\frac{5}{6} \sigma
