Circuit will be given in Complex$/$Frequency domain $$ No need to convert.

$$ Solve for requested current$($s$)$ and$/$or voltage$($s$)$ in the Complex$/$Frequency

domain $.$

$$ Show work, be neat, and clearly identify answer$($s$).$

$4$a$.$ Using Nodal Analysis at node n solve for the Phasor voltage Vo$($j$)$ in the circuit below.

$4$b$.$ Express Vo$($j$)$ in the time domain $($ i$.$e$.,$ Vo$($t$))$ assume $=1000$ rad$/$sec$.$

$4$c$.$ Solve for Io$($t$).$
