A long, horizontal wire is carrying a current I. A particle of mass m and charge q is fired horizontally at a speed v0. 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, µo, and the acceleration of gravity g. Figure 1 of 1 > Write down an explicit expression for the gravitational force acting on the particle. Express your answer in terms of m and the acceleration of gravity g. ► View Available Hint(s) 15.
