Question

A radio capacitor of variable capacitance is made of $n$ parallel plates each of area $A$ and separated from each other by a distanced. The alternate plates are connected together. The capacitance of the combination is.

\frac{n A \in _{o}}{d}

\frac{( n - 1 ) A \in _{o}}{d}

\frac{( 2 n - 1 ) A \in _{o}}{d}

\frac{( n - 2 ) A \in _{o}}{d}
