(8) A cosmic-ray proton in interstellar space has an energy of 16.0 MeV and executes a circular orbit 2530-12 (b) What If? The cosmic ray proton enters our solar system where the interplanetary magnetic field has a magnitude of 5.00 nT and is perpendicular to t * mERPSE10 28.2.OP.008.MI. MY NOTES ASK YOUR TEACHER P 6.0 Mev and executes a circular orbit having a radius equal to that of Mars' orbit around the Sun (2/28 , Jo!! m). What Is the magnetic field (in T) In that region of space? where the interplanetary magnetic field has a magnitude of 5.00 nT and is perpendicular to the velocity of the proton. What is the radius (In m) of the proton's circular orbit in this fleide
