The 10-cm-wide, zero-resistance slide wire shown in FIGURE P30.57 is pushed toward the 2.0 Ω 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?
