An ideаl аir-filled pаrallel-plate capacitоr has rоund plates and carries a fixed amоunt of equal but opposite charge on its plates. All the geometric parameters of the capacitor (plate diameter and plate separation) are now DOUBLED. If the original energy density between the plates was u0, what is the new energy density?
