b
we know that \(C=K \frac{A \varepsilon_0}{d}\) where \(K\) is constant Ais Area of crosssection \({ }^d \varepsilon_0\) is Permeability of tree Space add \(d\) is distance \(G / \omega\) Parallel Plates So \(c \propto \frac{1}{d}\) cis inversty Proportional to \(d\) so according to question \(d\) increase \(c\) decrease and we know \(v \alpha \frac{1}{c}, v\) is inversly Proportion to \(C\) so \(c\) decreases \(v\) increase

So Potential differente b/w Plates increase
