Question 1 A proton travels at a speed of 7.91x10' m/'s along the x-axis. What is the magnetic field at the point (0.00 cm,-2.00 cm, 0.00 cm) when the proton passes through the origin? O -3.16x1071= KT O 3.16x1071= KT O 3.87x1021 KT O -3.87x1031 KT Question 2 The figure shows a closed surface that has a line integral of the magnetic field of 1.00x10"- Tm. If 4 = 20.0 A. ( = 9.00 A and /4 = 20.0 A, what is the current flowing through (? 31.8 A, out of the page Q 31.8 A, into the page 9.80 A, out of the page 9.80 A, into the page Question 3 The two straight wires above are = 22.5 cm long, and = 7.00 cm apart have a current of /= 9.31 A flowing in the same direction through each of them. What is the force (magnitude and direction) that wire B exerts on wire A? 5.98x10"= N up O 5.57x10"= N down O 5.57x10"= N up O 5.98x10" N down
