Item 1
An electron is moving in the vicinity of a long, straight wire that
lies along the x-axis. The wire has a constant current
of 8.50 A in the -x-direction. At an instant when the electron is
at point (0,0.200m,0) and the electron?'s velocity is
vec(v)=(5.00\times 10^(4)(m)/(s))hat(i)-(3.00\times 10^(4)(m)/(s))hat(j).
Part A
