A circuit with a resistor, inductor and capacitor in series is resonant of 
If all the component values are now doubled, the new resonant frequency is:
still 
Explanation:
Let initially resistance, capacitance & inductance is R, C & L respectively and resonant frequency is 
.
Now, new resistance, capacitance & inductance
R’ = 2R
C’ = 2C
L’ = 2L
New resonant frequency 
Hence, 
So, resonance frequency is halved.
