In the figure, a conducting rod of length L= 34.0 cm moves in a magnetic field B? of magnitude 0.440 T directed into the plane of the figure. The rod moves with speed v= 4.00 m/s in the direction shown. (Figure 1)

a-When the charges in the rod are in equilibrium, which point, a or b, has an excess of positive charge?When the charges in the rod are in equilibrium, which point, a or b, has an excess of positive charge?

a

b

b-What is the direction of the electric field in the rod?What is the direction of the electric field in the rod?

from a to b

from b to a

c-When the charges in the rod are in equilibrium, what is the magnitude E of the electric field within the rod? Express your answer in volts per meter to at least three significant figures.

E=?V/m

d-Which point, a or b, has a higher potential?

a

b

Points a and b have the same potential.

e-what is the magnitude Vba of the potential difference between the ends of the rod? Express your answer in volts to at least three significant figures.

Vba=?V

f-What is the magnitude E of the motional emf induced in the rod? Express your answer in volts to at least three significant figures.

E=?V
