The potential difference between the plates of a parallel plate capacitors is 200 V.The area of each plate is 100 cm^2 and the distance between them is 1mm.If the medium between them is air,then calculate the charge taken by the capacitor.If there is a medium of dielectric Constant 2.5 between the plates,then what will be the potential difference for the same charge??? Answer-1.76?10^-8 C or 80V
