The conducting spherical shells shown in the figure are connected by a conductor. The capacitance of the system is
|
$4 \pi \varepsilon_0 \frac{a b}{b-a}$ $4 \pi \varepsilon_0 a$ $4 \pi \varepsilon_0 b$ $4 \pi \varepsilon_0 \frac{a^2}{b-a}$ |
$4 \pi \varepsilon_0 b$ |
Hence, the capacitance of the system is the capacitance due to outer sphere of radius b. ∴ C = 4πε0b (C) is correct choice. |
