In a chamber, a uniform magnetic field of 6.5 G `(1 G = 10^-4 T)`is maintained. An electron is shot into the field with a speed of `4.8 xx 10^6 m s^-1` normal to the field. Explain why the path of the electron is a circle. Determine the radius of the circular orbit. `(e = 1.5 xx 10^-19 C. m_e= 9.1x10^-31 kg)`
