An inductor of inductance 1.0H is connected in series with a capacitor of capacitance 2.0(mu F) in an a.c. circuit. to resonate
-
A.
112.5Hz -
B.
225.0Hz -
C.
323.5Hz -
D.
707.1Hz
Correct Answer: Option A
Explanation
fo = (frac{1}{2 pi sqrt{LC}} = frac{1}{2 times 3.14 sqrt{1 times 2 times 10^{-6}}})
= 112.5Hz
