Two identical charged spherical drops each of capacitance $C$ merge to form a single drop. The resultant capacitance

A

equal to $2C$

B

greater than $2C$

C

less than $2C$ but greater than $C$

D

less than $C$

Solution

${C^{'''}}\, = \,{n^{1/3}}C\, \Rightarrow \,{C^{'''}}\, = \,{2^{1/3}}C\,\, \Rightarrow \,2C\, > {C^{'''}}\, > C$
