At what speed would a proton need to circle the Earth at a height of 1000 km above the equator if the Earth's magnetic field is horizontal and directed north-south, with an intensity of 4.00 * 10-8 T? (The radius of the Earth is 6400 km and the charge and mass of the proton are q = 1.60 * 10-19 C and mp = 1.67 * 10-27 kg.Ignore relativistic corrections.)
