Question 3 L The two straight wires above are _ = 21.0 cm long, and d = 2.00 cm apart have a current of /= 7.20 A flowing in the same direction through each of them. What is the force (magnitude and direction) that wire A exerts on wire B? O 0.000109 N up O 0.000109 N down O 1.51x10"- N up O 1.51x10" N downQuestion 1 Wire 1 d, Wire 2 Two long straight wires are perpendicular to the page and separated by a distance d, = 1.50 cm. Wire 1 carries a current 4.50 A into the page. The magnetic field at point P, a distance dy = 4.85 cm below wire 2, is zero (0 T). What must be the current in wire 2? O 3.44 A, out of the page. O 4.50 A, out of the page. O 0 A, there is no current. O 14.6 A, into the page Question 2 The figure shows a closed surface that has a line integral of the magnetic field of 1.00*10" Tm. If 4 = 16.0 A, / = 13.0 A and /4 = 24.0 A, what is the current flowing through }? O 13.8 A, out of the page O 13.8 A, into the page O 27.8 A, into the page O 27.8 A, out of the page
