be r so original area A= πr2 noe r is doubled and d is also doubled so new area A2=π(2r)2= 4A also new distance d2= 2d so new capacitance Cn=4A/ε(2d) = 2A/εd = 2C as only geometric changes are done but charges on plates will rtemain same so original energy stored in capacitor Uo= 0.5(Q2/C) new energy stored in capacitor Uf = 0.5(Q2/Cn) = 0.5[0.5(Q2/C)] = 0.5(Uo)= Uo/2 so new energy stored in capacitor Uf =Uo/2 final answer a charge of 2.00 uC flows into the plates of a capacitor when it is connected
