Two Conducting Rails of Negligible Resistance Terminate in a Resistor $\varOmega$

question 52

Multiple Choice

Two conducting rails of negligible resistance terminate in a resistor of resistance R = 2.40 $\varOmega$ The rails are placed in a magnetic field B = 15.0 mT perpendicular to the plane of the rails.The magnetic field is uniform and time independent.The distance between the rails is w = 10.0 cm as shown in the figure.A conducting rod of negligible resistance slides frictionless on top of the two rails at a velocity v = 1.20 m/s + (3.4 m/s²) t,where t is the time,in seconds.The induced current in the circuit at t = 1.00 s is

• A)2.88 mA.
• B)1.81 mA.
• C)1.28 mA.
• D)0.978 mA.
• E)0.836 mA.
