A 12 pf capacitor is connected to 160 V battery. How much electrostatic energy is stored in the capacitor ?

Question

A 12 pf capacitor is connected to 50 V battery. How much electrostatic energy is stored in the capacitor ? If another capacitor of 6 pF is connected in series with it with the same battery connected across the combination, find the charge stored ind potential difference across each capacitor

Answer 1

=> V2=200/6=100/3 Volts.
