Answer the following questions:
What is so special about the combination e/m? Why do we not simply talk of e and m separately?
The basic relations for electric field and magnetic field are `(eV = 1/2 mv^2) and (eBv = (mv^2)/r) `respectively
These relations include e (electric charge), v (velocity), m (mass), V (potential), r(radius), and B (magnetic field). These relations give the value of velocity of an electron as (`v = sqrt(2v(e/m))` and `(v = Br (e/m))` respectively
