Problem 11: (10 points) A long straight wire suspended in the air carries a conventional current of 2.63 A in the-x direction as shown in Figure (the wire runs along the x axis). At a particular instant a proton at location (0, -0.0441,0) m has velocity (4x 105, 0, 0) m/s. (Consider the charge of the proton: q,-1.6x10-1⁹ C). 2 out 1.
