An electron traveling at relativistic speed moves perpendicular to a magnetic field of 0.20 π. Its path is circular, with a radius of 15 π. Find: (a) the momentum, (b) the speed, and (c) the kinetic energy of the electron. Recall that, in nonrelativistic situations, the magnetic force ππ£π΅ furnishes the centripetal force ππ£ 2βπ. Thus, since π = ππ£ it follows that π = ππ΅π and this relation holds even when relativistic effects are important.

b)
