A 25 cm rod moves at 3.8 m/s in a plane perpendicular to a magnetic field of strength 0.20 T. The rod, velocity vector, and magnetic field vector are mutually perpendicular, as indicated in the accompanying figure. B x X T 25 cm x XI X V x x x x X (a) Calculate the magnetic force on an electron in the rod (in N). (Enter the magnitude.) N (b) Calculate the electric field in the rod (in V/m). (Enter the magnitude.) V/m (c) Calculate the potential difference between the ends of the rod (in V). (d) What is the speed of the rod (in m/s) if the potential difference is 1.0 V? m/s A 25 cm rod moves at 3.8 m/s in a plane perpendicular to a magnetic field of strength 0.20 T.
