QUESTION #48 Sharing of Charges between Capacitors
A capacitor P with capacitance 10 times 10^-6 F is fully charged with a potential difference of 6.0 V and disconnected from the battery. The charged capacitor P is connected across another capacitor Q with capacitance 20 times 10^-6 F. The charge on capacitor Q when equilibrium is established will be alpha times 10^-5 C (assume capacitor Q does not have any charge initially), the value of alpha is ____.
