Phasor eqs.

## The Attempt at a Solution

[tex]i\,=\,\frac{50\,-\,V_1}{2\Omega}\,=\,\frac{V_1\,-\,V_2}{5\,j\,\Omega}\,=\,\frac{V_2}{20\,j\,\Omega}[/tex]

If I substitute [itex]V_1\,=\,0[/itex], then I get:

[tex]25\,=\,-\frac{V_2}{5\,j\,\Omega}\,=\,\frac{V_2}{20\,j\,\Omega}[/tex]

How do I use this to find [itex]\omega[/itex]?
