A car with a vertical radio antenna 75 cm long drives due west at 23 m/s. The Earth's magnetic field at this location has a magnitude of 5.9 10-5 T and points northward, 74° below the horizontal. Find the induced emf between the ends of the antenna.
I tried using the equation E=BvL with the different vector components. I also tried it without using the vector components and I got the same answer.
