Three long wires carry currents parallel to the X - axis, as shown in Fig4. The wires are at equal distances d= 20 cm from each other. Wires 1 and 3 lie in the xay plane. The currents in the figure are given by I, =2 A in the tx direction, I =4A " thetx direction, and Is = & A in the - * direction . The distances between the wires is d= 20 cm. 15 ) [05pts] The magnitude of the force per unit length in wire 2 is Fig . 4 a ) o 6) 4 x 10 14/m I ZA c) 8 x 10 -6 N /m I, = XA > ty d ) 1.6 * 10- 5 M/m +X () name of the above I = 4A 16)605 pty The force on wire a has direction on ) my b ) -y c )+z d) 2 e) Goabove the ty any (Hint : find the Net force per unit length on wire I via vector addition, taking into accound the forces between each pair of current carrying wires, is wires I and 2 , and wires 3 and 2 )
