I also have the formula Fe = Eq, but with that I do not know the E or the q.
I can go Fe = Fm , Eq=qvB, E=vB, v=E/B, v=Vq/B from there I don't know the q and I am not using the length of the wire (30.0m).
Homework Statement
A voltage of 1.50 V is induced in a 30.0 m long wire as it moves perpendicularly to a 3.50× 10–3 T magnetic field. At what speed is the wire moving?
Answer is 14.2 m/s
Homework Equations
Fm=IlB
Fm=qvB
I=q/t
Thanks for all of your help! :)
