The quality factor (Q value) of the circuit, when                 a series resonant circuit contains \[\text{L=}\frac{\text{5}}{\text{ }\!\!\pi\!\!\text{ }}\text{mH,}\,\text{C=}\frac{\text{200}}{\text{ }\!\!\pi\!\!\text{ }}\text{ }\!\!\mu\!\!\text{ F}\]and R= 100 \[\Omega \], will be  (source of emf e =200 sin 100 \[\pi \]t is applied to                 the circuit)

A)                  \[5\times {{10}^{-2}}\]                 

B)  \[5\times {{10}^{-5}}\]

C)                  \[\left( \frac{5}{\pi } \right){{10}^{-5}}\]                              

D)  \[\left( \frac{5}{\pi } \right){{10}^{-2}}\]
