A) \[356\text{ }cycle/h\]
B) \[356\text{ }cycle/s\]
C) \[356\times {{10}^{3}}cycle/s\]
D) \[3.56\text{ }cycle/s\]
Correct Answer: B
Solution :
Frequency of vibration for L-C circuit is given by \[n=\frac{1}{2\pi }\frac{1}{\sqrt{LC}}\]where L is coefficient of self-inductance, C the capacitance. Given, \[C=20\text{ }\mu F=20\times {{10}^{-6}}F,\] \[L=10\text{ }mH=10\times {{10}^{-3}}H\] \[\therefore \] \[n=\frac{1}{2\times 3.14}.\frac{1}{\sqrt{20\times {{10}^{-6}}\times 10\times {{10}^{-3}}}}\] \[\Rightarrow \] \[n=356\text{ }cycle/\text{ }s\]You need to login to perform this action.
