A series LCR circuit has a resonant angular frequency of 1.0×104rad s−1. When it is driven at 8.8×103rad s−1, the magnitude of the impedance equals 2R. The frequency 8.8×103rad s−1 is
a) Exactly at resonance
b) On the higher side of resonance
c) On the lower side of resonance
d) Indeterminate without knowing L and C
