A +6.00 µC charge is moving with a speed of 7.00 x 10^4 m/s parallel to a very long, straight wire. The wire is 5.00 cm from the charge and carries a current of 63.0 A in a direction opposite to that of the moving charge. Find the magnitude and direction of the force on the charge.
___________ mN
B = (4pi x 10^-7)/ 2piR
F = q0 v B sin theta
F = (0.000006)(70000)(0.000001257)(63.0)(1)/ 0.3142
F = 0.000033255 / 0.3142
F = 1.0584 x 10^-4 N
F = 1.0584 x 10^-1 mN
_X_ perpendicular to the wire and directed away from it
___ perpendicular to the wire and directed towards it
___ parallel to the current
___ anti-parallel to the current
___ perpendicular to the plane containing both the wire and the charge

Yes, I cheated and used my two right hands and the right hand rules.
Your response confuses me. Please clarify.
You are correct. I did the direction with the right hand rules (thumb in direction of + current). My direction is the same as yours.
Thanks!
