Two parallel plate capacitors of capacitances 2 μF and 3 μF are joined in series and the combination is connected to a battery of V volts. The values of potential across the two capacitors V1 and V2 and energy stored in the two capacitors U1 and U2 respectively are related as _________. Fill in the blank with the correct answer from the options given below.
1
\(\rm \frac{V_1}{V_2}=\frac{U_1}{U_2}=\frac{3}{2}\)
2
\(\rm \frac{V_1}{V_2}=\frac{U_1}{U_2}=\frac{2}{3} \)
3
\(\rm \frac{V_1}{V_2}=\frac{3}{2}\ and \ \frac{U_1}{U_2}=\frac{2}{3} \)
4
\(\rm \frac{V_1}{V_2}=\frac{2}{3}\ and \ \frac{U_1}{U_2}=\frac{3}{2} \)
