Q. Two identical charged spherical drops each of capacitance $C$ merge to form a single drop. The resultant capacitance is
A) Equal to $2C$
B) Greater than $2C$
C) Less than $2C$ but greater than $C$
D) Less than $C$
Explanation
(c) $C^{'} = n^{1/3}C \Rightarrow C^{'} = 2^{1/3}C \Rightarrow 2C > C^{'} > C$
