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 × 106 m s–1 normal to the field. (e = 1.6 × 10–19 C, me= 9.1×10–31 kg). Obtain the frequency of revolution of the electron in its circular orbit. Does the answer depend on the speed of the electron? Explain
