7/33= 7/837/33 12 x Student's name: Problem 1 (33 points): One long wire carries a current of i, = 21.04 to the left along the x axis. The second long wire carries a current of 12 = 44.0 A to the right along a line (y = 0.0280 m, z = 0). At certain instant of time a charge q = 2.00 x 10-6 C is located between two wires on a line (y = 0.0120 m, z 0) and 11 moves with a velocity of 1.50 x 106 m/s in the positive x-direction. a) What is the magnetic field, both the magnitude and the direction, due to the currently at the location of the charge q ? Use unit vectors i, j, k to indicate the direction of the magnetic field. (Vector k is directed out of the page.) b) What is the magnetic field, both the magnitude and the direction, due to the current 1, at the location of the charge q ? Again, use unit vectors i, j, k to indicate the direction of the magnetic field. c) What is the resultant magnetic field, both the magnitude and the direction, due to both the currents at the location of the charge q ? Again, use unit vectors i, j, k to indicate the direction of the magnetic field. d) What is the magnetic force on the charge q, both the magnitude and the direction? Use unit vectors L.), k to indicate the direction of the magnetic force. e) Suppose now a uniform electric field is applied to allow the charge move between the wires undeflected. What should be this electric field, both the magnitude and the direction? Use unit vectors i, j, k to indicate the direction of the electric field. 12 Il
