A diode AM detector with the output circuit consisting of

R = 1\;\mathrm{kW}

and

C = 1\;\mathrm{\mu F}

would be more suitable for detecting a carrier signal of

View answer and explanation

Correct option: D

10 kHz

Option D (

\frac{1}{3} \pi q f l^2

) is correct because the magnetic moment is calculated by integrating the current due to each infinitesimal charge element along the rod.
