Two particles have the same linear momentum, but particle has four times the charge of particle . If both particles move in a plane perpendicular to a uniform magnetic field, what is the ratio of the radii of their circular orbits?
A cosmic-ray electron moves at perpendicular to Earth’s magnetic field at an altitude where the field strength is . What is the radius of the circular path the electron follows? Electron mass is kg and electron charge is C.
Find the radius of curvature of the circular path followed by a 25.0-MeV-energy proton that enters a region perpendicular to a 1.20-T magnetic field.
