### Problem Description**Context:**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 depicted in Figure 1.**Question:**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 \( g \).### Task Part C**Objective:**Write down an explicit expression for the gravitational force acting on the particle.**Instructions:**Express your answer in terms of \( m \) and the acceleration of gravity \( g \).**Input Box:**A space to input your expression for the gravitational force \( F_g \).**Hints:**Options to view available hints to assist in solving the problem.### Explanation of Diagrams and InterfaceThere is a figure (Figure 1) mentioned, which likely illustrates the setup involving the wire, particle, and vectors showing forces or velocities.
