Concept explainers
To prove: Mass of an ion in a spectrometer is
Given:
Ion accelerates by a voltage V .
R is the radius of the ion and q is the charge of the ion.
Formula used:
The magnetic force is
Calculation:
The magnetic force is equal to the centripetal force for the given situation. So,
The energy of ion is,
Kinetic energy is,
So,
(1)
Now,
Substitute the value of v from equation (1),
Squaring both sides,
