MHT CET Physics question
A coil of 4 mH and a capacitor of F are in series with an a.c. source along with resistance. If inductive reactance is equal to capacitive reactance then the angular frequency (in rad/s) of source is
Answer: (A)
Solution
\frac{1}{\sqrt{LC}}\frac{1}{\sqrt{4×10^{-3}×10^{-5}}}\frac{1}{2×10^{-4}}$
