A 1.00 uF capacitor is connected in parallel with a 2.00 uF capacitor. The 1.00 uF capacitor carries a charge of +10.0 uC on one plate, which is at a potential of 50.0 V. Find
(a) the potential on the negative plate of the 1.00 uF capacitor;
(b) the equivalent capacitance of the two capacitors;
(c) the charge on the negative plate of the 2.00 uF capacitor.
