A)
Using right hand rule of cross product and Lorentz force we can find that charge carriers that electrons will have force F= q(v x B) = -e(v x B) towards the center of the circle as shown in the below figure.
Thus the magnetic force FB on electron will be towards the center of the circle.
B)
C)
Electric field direction is from +ve charges to negative charges. Thus E is shown in the above figure away from the center.
D)
FE = - FB = - q(v x B) = -[-e(v x B)] = evB
E = FE/e = vB
Since v=wL
E = wBL
