Chapter 43, Problem 56P
To determine

To show that:

(a) if the expressions for Maxwell’s speed distribution energies for molecules in a gas is as given in Chapter 19, then the most probable energy is given by

Kp = ½ kT

Also verify the result with the energy distribution curve given in Fig 43.10 in the textbook, for T = 1.5x107K.

(b) the most probable speed is given by

vp= 2kTm,

then find its value for protons at T = 1.5x107K.

(c) the energy corresponding to the most probable speed (which is not the same as most probable energy) is

Kv, p = kT

And locate this quantity of the curve given in Fig 43.10.

A Van de Graff generator, if the metal sphere on the Van de Graff has a charge of 0.14 Coulombs and the person has a mass of 62 kg, how much excess charge would the person need in order to levitate at a distance 25 cm from the center of the charged metal sphere? Assume you can treat both the person and the metal sphere as point charges a distance 25 cm from each other using Coulomb's Law to calculate the electrical force.  Give your answer as the number of Coulombs
