Question

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

• A. equal to 2 C
• B. greater than 2 C
• C. less than 2 C but greater than C
• D. less than C

Answer 1

Answer: (C)

$C^{\prime \prime }=n^{1/3}C$
$\Rightarrow C^{\prime \prime }=2^{1/3}C$
$\Rightarrow 2C<C^{\prime \prime }>C$
