Question 1) A 110 pF capacitor is charged to a potential difference of 54 V, and the charging battery is disconnected. The capacitor is then connected in parallel with a second (initially uncharged) capacitor. If the measured potential difference across the first capacitor drops to 20 V, what is the capacitance of this second capacitor? Question 2) Is in the image!
