MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER (a) The figure below shows two parallel conducting rails 17.6 cm apart, connected by a resistor with resistance R3 = 5.00 . Two metal rods with resistances R4 = 12.80 and R2 = 15.0 Slide along the rails with negligible friction. Rod R, slides to the left at constant speed V1 = 4.00 m/s, while rod R, slides at speed v2 = 2.00 m/s. The rods and rails are in the presence of a uniform magnetic field pointing into the page, perpendicular to the plane of the rails, with a magnitude of Bin -0.0100 T X X X X X X X X X X X X XXX XBX XX X X X XX x x * R ** * * * * * * * * XXXXXXXXX R RO What are the magnitude (in A) and direction of the current through resistor Ry? magnitude direction ---Select- HA (6) What If? What are the magnitude (in A) and direction of the current through resistor R, if the rods move inward, instead of outward, with the same speeds as in part (a)? magnitude NA direction Select Need Help?
