The two conducting rails in the drawing are tilted upward so they each make an angle of 30.0° with respect to the ground. The vertical magnetic field has a magnitude of 0.040 T. The 0.29-kg aluminum rod (length - 1.6 m) slides without friction down the rails at a constant velocity. How much current flows through the rod? Number i Conducting Units 16m-

An electron moves in a circular path perpendicular to a magnetic field of magnitude 0.230 T. If the kinetic energy of the electron is 3.70 x 10-19 J, find the speed of the electron and the radius of the circular path. (a) the speed of the electron 9.02e5 ✔ m/s (b) the radius of the circular path Your response is off by a multiple of ten. um
