Answer the following questions: (b) What is so special about the combination e/m? Why do we not simply talk of e and m separately? |
| Answer» Solution :Both the BASIC relations `E V = (1//2) m v^(2) or e E = m a and e B v =m v^(2)//R`, for electric and MAGNETIC fields, respectively, show that the dynamics of electrons is determined not by e, and m SEPARATELY but by the combination e/m. | |
