A 170 pF capacitor is charged to a potential dissimilarity of 90 V, and the charging battery is disconnected. The capacitor is then connected in parallel by a second (initially uncharged) capacitor. If the measured potential dissimilarity drops to 80 V, what is the capacitance of this second capacitor?
