Dear Student
Given Potential difference across capacitor=50V, distance between plates=5mm=5×10-3mEnergy in unit volume that is area×distance=1A×d=1so A=1dCapacitance,C=ε0Ad=ε0d2=8
8×10-12(5×10-3)2=0 325×104Farad(ε0=8
8×10-12Fm-1)Energy=12CV2=12×0
325×50×50=440JHope this information will clear your doubts about topic
