Question

Consider a hypothetical dN/du Vs u graph for an ideal gas particles. The root mean square speed of given distribution is–

• A. $\sqrt{\frac{8}{3}}$
• B. $\frac{2}{\sqrt{3}}$
• C. $\frac{4}{\sqrt{3}}$
• D. None

Answer 1

Answer: (A)

$\sqrt{\frac{8}{3}}$

Answer 2

V_rms = $\frac{\int_{0}^{4}{u^{2}dN}}{\int_{0}^{4}{dN}}$
