Answer:

Frequency, f = 7.57 Hz

Explanation:

It is given that,

Capacitance, [tex]C=3\ \mu F=3\times 10^{-6}\ F[/tex]

Capacitive reactance, [tex]X_C=7\ k\Omega=7\times 10^3\ \Omega[/tex]

We need to find the frequency. The capacitive reactance of the capacitor is given by :

[tex]X_C=\dfrac{1}{2\pi fC}[/tex]

f is the frequency

[tex]f=\dfrac{1}{2\pi CX_C}[/tex]

[tex]f=\dfrac{1}{2\pi \times 3\times 10^{-6}\ F\times 7\times 10^3\ \Omega}[/tex]

f = 7.57 Hz

Hence, this is the required solution.
