Mass Spectrometer |
Various methods can be used to measure the mass of an atom. One possibility is through the use of a mass spectrometer. |
The basic feature of a Banrbidge mass spectrometer is illustrated in figure. A particle carrying a charge +q is first sent through a velocity selector and comes out with velocity v = E/B. |
The applied electric and magnetic field satisfy the relation E = vB so that the trajectory of the particle is a straight line. |
Upon entering a regin where a second magnetic field \[{{\overrightarrow{B}}_{0}}\] pointing into the page has been applied, the particle will move in a circular path with radius r and eventually strike the photographic plate. |
A) By accelerating them through electric field
B) By accelerating them through magnetic field
C) By accelerating them through electric and magnetic field
D) By applying a high voltage.
Correct Answer: C
Solution :
In mass spectrometer, the ions are sorted out by accelerating them through electrical and magnetic field.You need to login to perform this action.
