Practice Question
In a chamber, a uniform magnetic field of 4.5 G \((1G = 10^{-4}T)\) is maintained. An electron is shot into the field with a speed of \(4.8 * 10^6\) 106 m/s normal to the field.

Find the radius of the circular orbit? Also obtain the frequency of revolution of the electron in its circular orbit?(\(e=1.6 * 10^{-19}C,m_e=9.1 * 10^{-31}kg\))choose an approximate value.
