17.35: A metal bar is moving to thek6ruj fhd8sl(fz wm4,i 7 5e:x leftk43y9dli(s* k(/6lvq ssnuplt1kgh . across a set of frictionless conducting rails as seen in the figure. Throughout the region between the rails, there is a uniform magnetic field directed into the plane of the page. The resistors labeled X and Y are identical. Which one of the following choices correctly indicates the direction of the conventional c*4p6k(. 19k /(gq ds3 ylsushllvtinkurrent in the resistors and the relation between the magnitude of the currents through each resistor at the instant shown?
A. Current through X is Up the plane of the page Current through Y is Up the plane of the page Relation between Currents is $I_X\:>I_Y$
B. Current through X is Up the plane of the page Current through Y is Up the plane of the page Relation between Currents is $I_X\:=I_Y$
C. Current through X is Up the plane of the page Current through Y is Down the plane of the page Relation between Currents is $I_X\:>I_Y$
D. Current through X is Down the plane of the page Current through Y is Down the plane of the page Relation between Currents is $I_X\:=I_Y$
E. Current through X is Down the plane of the page Current through Y is Down the plane of the page Relation between Currents is $I_X\:>I_Y$
