An electron and a proton each have a thermal kinetic energy of 3kbt/2. calculate the de broglie wavelength of each particle at a temperature of 1800 k. (kb is boltzmann's constant, 1.38x10^-23 j/k). (1) wavelength of the electron = m (2) wavelength of the proton = m

Given:

Thermal Kinetic Energy of an electron,

= Boltzmann's constant

Temperature, T = 1800 K

Solution:

Now, to calculate the de-Broglie wavelength of the electron, :

             (1)

where

h = Planck's constant =

= momentum of an electron

= velocity of an electron

= mass of electon

Now,

Kinetic energy of an electron = thermal kinetic energy

                   (2)

Using eqn (2) in (1):

Now, to calculate the de-Broglie wavelength of proton, :

                            (3)

where

= mass of proton

= velocity of an proton

Now,

Kinetic energy of a proton = thermal kinetic energy

                              (4)                    

Using eqn (4) in (3):

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
