Please add description.The distance between the plates of a charged parallel plate copacitor is `5cm` and electric field inside the plates is `200V cm^(-1)`. An uncharged metal bar of width `2 cm` is fully immersed into the capacitor. The length of the metal bar is same as that of plate of capacitor. The voltage across capacitor after the immersion of the bar is-
