A flat conducting plate of width 0.010m carries electrons that drift at an average speed of 2.0×10−2m⋅s−1 while a 0.50T magnetic field is directed perpendicular to the plate. What is the magnitude of the Hall voltage that develops across the width of the plate?
a) 1.0×10−2V
b) 1.0×10−4V
c) 5.0×10−3V
d) 1.0×10−6V
