TG EAPCET 2025 (Online) 2nd May Morning Shift | Capacitor Question 5 | Physics

As shown in the figure, a dielectric of constant $K$ is placed between the plates of a parallel plate capacitor and is charged to a potential $V$ using a battery. If the dielectric is pulled out after disconnecting the battery from the capacitor, the final potential difference across the plates of the capacitor is
