Question
The figure below shows two parallel conducting rails 18.8 cm apart, connected by a resistor with resistance
R3 = 5.00 Ω.
Two metal rods with resistances
R1 = 12.8 Ω
and
R2 = 15.0 Ω
slide along the rails with negligible friction. Rod
R1
slides to the left at constant speed
v1 = 4.00 m/s,
while rod
R2
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.
Two parallel horizontal rails are vertically aligned and connected through their centers with a vertical wire containing resistor R3. A vertical rod labeled R1 lies vertically across the sides of the rails to the left of R3. An arrow labeled (vector v1) extends from the center of this left rod to the left. A vertical rod labeled R2 lies vertically across the sides of the rails to the right of R3. An arrow labeled (vector v2) extends from the center of this right rod to the right. The label (vector Bin) is to the left of R3. The area between the rails is filled with evenly-spaced x symbols.
What are the magnitude (in µA) and direction of the current through resistor
R3?
