A capacitance C and an inductance L are operated at the same angular frequency

A capacitance C and an inductance L are operated at the same angular frequency. (a) At what angular frequency will they have the same reactance? (b) If L = 5.00 mH and C=3.50μFC=3.50μF, what is the numerical value of the angular frequency in part (a), and what is the reactance of each element?
