2. A certain charged particle in the Earth's upper atmosphere has a speed of 6.00 x 10$ m/s. The Earth's magnetic field at that location has a value of B = 4.88 x 105 T. The particle's velocity is perpendicular to the magnetic field and its circular path has a radius of 7.00 cm. (a) Find the amount of charge on the particle, q. (b) Calculate the time it takes for the electron to move in one complete circle. (mass of electron: m, = 9.1 x 10-31 kg )
