(a) A monoenergetic electron beam with electron speed of 5.20xx10^(6)ms^(-1) is subjected to a magnetic field of 1.30xx10^(-4)T , normal to the beam velocity. What is the radius of the circle traced by the beam, given e//m for electron equal 1.76xx10^(11)C.kg^(-1) . (b) Is the formula you employ in (a) valid for calculating radius of the path of 20 MeV electrons beam? If not, in what way is it modified!
