Question
Here is the question:Assume that Earth’s magnetic field is everywhereperpendicular to the path of a proton and that Earth’s magnetic field has an intensity of 3.86× 108 T. What speed would a proton need toachieve in order to circle Earth 1870.0 km abovethe magnetic equator?Answer in units of m/s.
i have to use utexas, an online homework site, and i triedmaking km to meters and setting Force of the magnetic field toCentripetal force, but it was wrong. help! Here is the question:
