A series RLC circuit is observed at two frequencies. At $$\omega_1$$ = 1k rad / s, we note that source voltage $$V_1=100\angle0^\circ V$$ results in a current $$I_1=0.03\angle31^\circ\;A$$. At $$\omega_2$$ = 2 k rad/s, the source voltage $$V_2=100\angle0^\circ\;V$$ results in a current $$I_2=2\angle0^\circ\;A$$. The closest values for R,L,C out of the following options are
A
R = 50W;L = 25mH;C =10μF;
B
R = 50W;L =10mH;C = 25μF;
C
R = 50W;L = 50mH;C = 5μF;
D
R = 50W;L = 5mH;C = 50μF;
