Capacitance of a parallel plate capacitor
$C=\frac{\varepsilon_{0} A}{d} \quad \ldots \text { (i) }$
Also capacitance = potential difference$/$charge $......(ii)$
When battery is disconnected and the distance between the plates of the capacitor is increased then capacitance increases and charge remains constant.
since capacitance $=$ potential difference/charge
$\therefore$ Potential difference increases.
