The 10cm-wide ,zero-resistance slide wire shown in the figure which is shown at ‘click here’ is pushed toward the 2.0 ohm resistor at a steady speed of 0.50 m/s .The magnetic field strength is 0.50 T .

a) How big is the pushing force ?

b) How much power does the pushing force supply to the wire ?

c) What are the direction and magnitude of the induced current ?

d) How much power is dissipated in the resistor ?
