Question
Chapter 20, Problem 20.6QAP
Interpretation Introduction
Interpretation:
The accelerating voltage required to direct singly charged ions of mass 5000 through the described instrument is to be stated.
Concept introduction:
The accelerating voltage is the voltage or the potential difference that causes a charge to be accelerated. As the accelerating voltage increases, the electrons travel with a higher velocity and become more energetic. These voltages are generally applied in the particle accelerators.

Q9
A 2993.72 m/z ion is accelerated into the 1.85 m flight tube of a linear time-of-flight mass spectrometer with an accelerating
voltage of 10.0 kV. How long will it take the ion to drift through the flight tube and reach the detector?
t =
(b) A system with chemical potential u = 12.5 meV contains identical particles each with integer spin and has a single
quantum state at energy E, = 0 meV. The temperature of the system is fixed at 290 K.
To three significant figures, what is the ratio Pg/P1, where P is the probability of finding a single particle in the state
Eo, and P3 is the probability of finding 3 particles in this state?
