What is the velocity of electrons moving in the beam of a Teltron tube?A beam of electrons passes into a region of uniform magnetic field of flux density 1 mT. The field causes the electrons to travel in a circular path of radius 3 cm. Calculate the velocity of the electrons.
charge of an electron = 1.6 x 10-19 C
Mass of an electron = 9.1 x 10-31 kg
