A copper rod of mass m = 1.08 kg rests on two horizontal rails a distance L = 0.923 m apart and carries a current of /= 49.0 A from one rail to the other. A top view and a side view are shown in the figure. The coefficient of static friction between rod and rails is µ = 0.640. What are the (a) magnitude and (b) angle (relative to the vertical) of the smallest magnetic field that puts the rod on the verge of sliding?
