A 7.4 mu F capacitor ischarged by a 110 V battery (see the figure a) and then isdisconnected from the battery. When this capacitor C1 is thenconnected (see the figure b) to a second (initially uncharged)capacitor, C2, the final voltage on each capacitor is 20 V. What is the value of C 2? [Hint: charge is conserved.]
