A long, horizontal wire is carrying a current \( I \). A particle of mass \( m \) and charge \( q \) is fired horizontally at a speed \( v_0 \). The initial velocity of the particle is parallel to the wire, and its initial position is a distance \( r \) directly below the wire, as shown in Figure 1. What initial speed must the particle have for it to travel in a straight line? Do not ignore gravity. Express your answer in terms of \( I, m, q, r, \mu_0 \), and the acceleration of gravity \( g \).

**Part I**

Determine at what initial speed \( v_0 \) the particle will travel in a straight horizontal line. 

*Express your answer in terms of some, all, or none of the variables \( m, q, v_0, I, r \), and the constants \( g, \mu_0 \), and \( \pi \).*
