Homework Help: physics

Posted by Sandhya on Sunday, October 12, 2008 at 9:53am.

What is the force on an electron moving at v = 2.5*10^5 m/s away from a long wire,3mm from the electron, carrying a 12 A current? Give the magnitude & direction of the force.
I calculated mag induction using
B = u0I/2(pi)*a and
force on the electron using
F = Bqv where q is the electron charged(assumed)
The force acts opposite to the direction of electron motion & towards the centre
Am I right?
