In Fig. 16.136, the rod moves with a speed of 1.8m/s, is 24.0cm long, and has 2.22 resistance. The magnetic field is 0.35T and the resistance of the U- shaped conductor is 26.02 at a given force needed to keep the rod's velocity constant at that instant. Caleulate (a) the emf induced; (b) the current flowing in the U-shaped conductor, and (c) the external force needed to keep the rod's velocity constant at that instant.

Exercise 01
In Fig. 16.136, the rod moves with a speed of 1.8m/s, is 24.0cm long, and
has 2.20 resistance. The magnetic field is 0.35T and the resistance of the U-
shaped conductor is 26.02 at a given force needed to keep the rod's velocity
constant at that instant. Calculate (a) the emf induced; (b) the current flowing
in the U-shaped conductor, and (c) the external force needed to keep the rod's
velocity constant at that instant.
