7. A capacitor of capacitance C and an inductor of inductance L are connected on both ends, the resonance angular frequency is: (A)LC (B)\( (LC)^{1/2} \) (C)\( (LC)^2 \) (D)\( (1/LC)^{1/2} \) (E)L/C

9. In the right figure, \( R_1 = 5\Omega \), \( R_2 = 10\Omega \), \( R_3 = 15\Omega \), \( C_1 = 5\mu F \), \( C_2 = 10\mu F \), and the ideal battery has an emf \( \varepsilon = 20V \). In steady state, the total energy stored in the two capacitors is: (A)\( 2.78\times10^{-5} \) J (B)\( 1.12\times10^{-4} \) J (C)\( 2.22\times10^{-4} \) J (D)\( 2.50\times10^{-4} \) J (E)\( 4.72\times10^{-4} \) J

(A)LC
(B)\( (LC)^{1/2} \)
(C)\( (LC)^2 \)
(D)\( (1/LC)^{1/2} \)
