a long straight wire carries a current of 2A. an electron travels with a speed of 4*10^4 m/s parallel to the wire at a distance of 0.1 metre from it. what force does the magnetic field exert on the moving electron

2. Relevant equations

what formula should i use? is it f= BqV SIN[tex]\theta[/tex] or f= BIl sin[tex]\theta[/tex]

or f=4*3.14*10^-7* I1*I2* L)/(2*3.14*a)
