The distance between the plates of a parallel-plate capacitor is 0.05 m. A field of \[3\times {{10}^{4}}V/m\] is established between the plates. It is disconnected from the battery and an uncharged metal plate of thickness 0.01 m is inserted. What would be the potential difference (in kv) if a plate of dielectric constant \[K=2\] is introduced in place of metal plate?
