Thanks so much for the reply. The initial position is (0,0). The question was worded "charge is moving initially at 1 x 10^6 m/s" I'm sorry I'm a little vague but this was a test question and I obviously don't have it in front of me.
BTW, in order to calculate where it hit the x-axis, I used...
A point charge is moving at 1 x 10^6 meters per second. At the origin (0,0), a magnetic field of 1 T is applied into the page. The charge = 1.6 x 10^/10 C.
1) Calculate the force.
2) Calculate the exact location it hits the X intercept.
3) Calculate the time is takes to hit the X intercept...
