Three charged particles are fixed in place at the vertices of an equilateral triangle of side length $s$, as shown in the figure. The particles have the charge values indicated. Points $P_1$ and $P_3$ are each located at the midpoint of a side of the triangle, and Point $P_2$ is equidistant from all three particles. Which of the following correctly ranks the electric potentials $V_1$, $V_2$, and $V_3$ at points $P_1$, $P_2$, and $P_3$ respectively?
$V_1 = V_2 = V_3$
$V_1 > V_2 > V_3$
$V_3 > V_2 > V_1$
$V_3 > V_1 > V_2$
