at 3.68100017 kHz the reactance in a circuit of a 9 uF capacitor and an inductor are equal in magnitude. what is the value of the inductor?

a. .000020 H
b. .000020 mH
c. .000021 uH
d. .000021 mH

Xl = Xc = 1/6.28FC.
Xl = 1/(6.28*3681*9*10^-6) = 4.807 Ohms
Xl = 6.28FL. = 4.807.
L = 4.807 / (6.28*3681) = 0.00021 h. =0.21 mH.

My answer don't agree with any of the
given answers.
