A 0.480 kg, 37.5 cm long metal rod is sliding down two metal rails that are inclined 42.0° to the horizontal. The rails are connected at the bottom so that the metal rod and rails form a loop that has a resistance of 52.0 Ω. There is a 2.00 T vertical magnetic field throughout the region of the rails. The rod starts from rest and there is no friction between the rod and the rails a) (3 points) Find an...
