Electric Potential & Equipotentials

Two metal sphere of radius $R$ and $3R$ have same surface charge density $\sigma$ . If they are brought in contact and then separated, the surface charge density on smaller and bigger sphere becomes $\sigma_1$ and $\sigma_2$ , respectively. The ratio $\frac{\sigma_1}{\sigma_2}$ is.

Show answer and solution

Answer: (d)

After contact both are at the same potential: $\sigma_1 R = \sigma_2(3R)$ .
$\dfrac{\sigma_1}{\sigma_2} = \dfrac{3R}{R} = 3$
So the answer is (d) 3.
