Answer:
1917723.40119 m/s
Explanation:
m = Mass of deuteron = [tex](1.637+1.675)\times 10^{-27}=3.312\times 10^{-27}[/tex]
k = Boltzmann constant = [tex]1.381\times 10^{-23}\ J/K[/tex]
T = Temperature = [tex]2.94\times 10^8\ K[/tex]
RMS velocity is given by
[tex]V_r=\sqrt{\dfrac{3kT}{m}}\\\Rightarrow V_r=\sqrt{\dfrac{3\times 1.381\times 10^{-23}\times 2.94\times 10^8}{3.312\times 10^{-27}}}\\\Rightarrow V_r=1917723.40119\ m/s[/tex]
The RMS velocity of the deutrons is 1917723.40119 m/s
