A conducting rod of mass M slides without friction to the right on conducting rails. The rails are distance d apart and are connected by resistor R. A uniform, constant magnetic field of magnitude B points into the page. The rod has an initial velocity v_0. (No external, mechanical force is applied to the rod.)
a) What is the induced emf as a function of instantaneous velocity v? (Give your answer in terms of v and the given quantities.)
b) Current flows in a loop through the resistor, the rod, and the connecting rails. What are the magnitude and direction of the induced current as a function of velocity v?
c) What is the force on the rod? Give magnitude and direction.
d) Show that the velocity as a function of time is v(t) = v_0e^(-at) where a = B^2d^2/(MR)
e) What is the total energy dissipated in the resistor over all time?
