Question:

In Fig 21-12, the rod moves with a speed of 1.6 m/s, is 30.0 cm long, and has a resistance of 2.5 Ω. The magnetic field is 0.35 T, and the resistance of the U-shaped conductor is 25.0 Ω at a given instant. Calculate.
(a) The induced emf,
(b) The current in the U-shaped conductor, and.
(c) The external force needed to keep the rod’s velocity at that instant.
