3. Two infinitely extended conducting planes physically meet at the origin and form a wedge of opening angle $45^{\circ}$. Although they touch geometrically, the two planes are electrically insulated from each other so that each can be maintained at an independent constant potential. One plane is held at potential $0$, and the other is held at potential $V_{0}$. Determine the electrostatic potential at a point $P$ located inside the wedge at angular position $15^{\circ}$ (for any $r > 0$). (A) $\frac{V_0}{\sqrt{3}}$ (B) $\frac{V_0}{3}$ (C) $\frac{V_0}{\sqrt{3}r}$ (D) $\frac{V_0}{3r}$
