Electric Potential & Equipotentials

Two spheres A and B of radius $a$ and $b$ respectively are at the same electric potential. The ratio of the surface charge densities of A to that of B is

Show answer and solution

Answer: (c)

For a sphere $V = \dfrac{kQ}{R} = \dfrac{\sigma R}{\varepsilon_0}$ .
Same $V$ : $\sigma_A a = \sigma_B b$
$\dfrac{\sigma_A}{\sigma_B} = \dfrac{b}{a}$
So the answer is (c).
