Two capacitors of capacitance 2muF and 3muF respectively are charged to potential difference 20 V and 40 V respectively. Now the capacitors are connected in series with a resistance such that the positively charged plate of one capacitor is connected to the positively charged plate of the other. The initial current through the resistance is I_(0) . The potential difference across the 2muF capacitor at the instant the current has reduced to (I_(0))/(2) is_______ V.
