fr = 1/2π √(LC).
L = 20 mH.
C = in series. so (C1+C2) /(C1C2) = 33.33nF.
substitute: fr = 1/2π √(LC).
fr = 1/2π √([20 m] x [33.33n]).
And the answer: 6.164kHz.

Capacitors are series so total capacitance is 0. 005/0. 15uf, inductance is 20mh, frequency is 1/2pi. sqrtLC.

Write equation for the tank circuit of the above circuit. Capacitors are connected in the series and its equation will be (1/C1+1/C2) and Inductor is in parallel to these capacitors, therefore total equation will f0=1/ (2pi*squrt ( (1/L) + ( (C1+C2) /C1C2) ) ).
