Problem 2 (PPP 167). A homogeneous magnetic field B is perpendicular to a track inclined at
an angle α to the horizontal. A frictionless conducting rod of mass m and length ℓ straddles the
two rails as shown.
How does the rod move, after being released from rest, if the circuit is closed by (a) a resistor of
resistance R, (b) a capacitorof capacitance C, or(c) a coil of inductance L? In all cases, neglect the
self-inductance of the closed loop formed, i.e. neglect the flux that its current puts through itself.
