An electron is rotating with constant speed of `6 xx 10^7 m//s` in a constant magnetic field `6 xx 10^(-4)`. Find out the frequency and radius of its circular path.

If an electron is moving with a velocity of 10^(-7)m.s^(-1) at right angles to a magnetic field of strength 10^(-3)T , determine the magnetic force acting on the electron and the radius of the circular path it describes. Given, mass of an electron =9.1xx10^(-31)kg , electronic charge =1.6xx10^(-19)C .

The radiation corresponding to 3 to 2 transition of hydrogen atom falls on a metal surface to produce photoelectron . These electrons are made to enter a magnetic field of 3xx10^(-4) T. if the radius of the largest circular path followed by these electrons in 10/0 mm, the work function of the metal is close to
