The aurora is caused when electrons and protons, moving in the earth’s magnetic field of  ≈5.0×10^−5 T, collide with molecules of the atmosphere and cause them to glow. a.  What is the frequency of the circular orbit for an electron with speed 1.0×10^6 m/s? Assume that the electron moves in a plane perpendicular to the magnetic field. b.  What is the frequency of the circular orbit for a proton with speed 5.0×10^4 m/s?

An electron is traveling with a constan velocity vo in the presence of a uniform electric mg field E-Ek, where E- e (Here, m denotes the mass of the electron and e denotes its charge. g denotes the acceleration due to gravity). Gravity acts in the -Z direction. At t=0, when the electron is at the origin, a uniform magnetic field BB+BJ is switched on. Here. B, and B, are fixed positive BB. The coordinates of the point where the electron intersects the X-Y plane constants and B for the first time after t=0 are given by: 2amy B Zamy BB e (A) (C) 2 e B 2AMY, B B (B) (D) 2amv, B.B. e B 2rum BB B Lamy B.B B 2am B B
