Q54 / 60 · IAT (IISER) 2019 · Physics

A capacitor with capacitance $C_0$ consists of two concentric spherical conductors. If the radii of the inner and the outer spherical conductors are halved, what is the new capacitance?

Correct answer
A
$C_0 / 2$
B
$4 C_0$
C
$C_0$
D
$C_0 / \sqrt{2}$

Hence, the correct answer is option: 'A'.
