Suppose we have two infinitely long parallel wires separated by carrying identical currents, i. a third parallel wire of length /, mass m, and current i3 is being levitated above by the two infinitely long wires. (a) if we assume that the infinite wires have current flowing in the +z-direction (out of the page), which direction is the current in the third wire flowing? explain your reasoning. (b) provide an expression for the force of one of the infinitely long wires on the levi- tated wire. express your answer in terms of given variables (no numbers) and appropriate constants. assume that all wires are separated by the same distance a. (c) what must the current be in the infinite wires in order to accomplish the setup desc a distance of a and ed in part (b)? suppose a 2cm, 15m, m = 2g, and i3 =10a

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
