In a chamber, a uniform magnetic field of 6.5 G (1G=10−4T) is maintained. An electron is shot into the field with a speed of 4.8×106ms−1 normal to the field. Explain why the path of the electron is a circle?
Determine the radius of the circular orbit. (e=1.5×10−19C,me=9.1×10−31kg).
Also obtain the frequency of revolution of the electron in its circular orbit. Does the answer depend on the speed of the electron? Explain.
