A parallel plate capacitor of capacitance \( 2 \, \text{F} \) is charged to a potential \( V \), The energy stored in the capacitor is \( E_{1} \). The capacitor is now connected to another uncharged identical capacitor in parallel combination. The energy stored in the combination is \( E_{2} \). The ratio \( {E_{2}}/{E_{1}} \) is:
