Two capacitors $C_1$ and $C_2$ are charged to $120\, V$ and $200\, V$ respectively. It is found that by connecting them together,the potential on each one can be made zero. Then:

$\sinh ^{-1} 2 + \sinh ^{-1} 3 = x \Rightarrow \cosh x$ is equal to

All capacitors used in the diagram are identical and each is of capacitance $C$. Then the effective capacitance between the points $A$ and $B$ is
