A) \[18kHz-30kHz\]
B) \[63kHz-75kHz\]
C) \[442kHz-466kHz\]
D) \[13482kHz-13494kHz\]
Correct Answer: C
Solution :
\[w=\frac{1}{\sqrt{LC}}\] \[=\frac{1}{\sqrt{49\times {{10}^{-6}}\times \frac{2.5}{10}\times {{10}^{-9}}}}\] \[=\frac{1}{7\times 5\times {{10}^{-8}}}=\frac{{{10}^{8}}}{7\times 5}=w\] \[=\frac{{{10}^{8}}}{7\times 5}=2\pi \times f=2\times \frac{22}{7}\times f\] \[\frac{{{10}^{8}}}{22\times 10}=f\] \[\frac{{{10}^{7}}}{22}=f\] \[\frac{{{10}^{4}}}{22}kHz=f\] \[f=454.54kHz\] For frequency range \[454.54\pm 12kHz\] \[442kHz-466kHz\]You need to login to perform this action.
