Question

To find out degree of freedom, the expression is

• A. $f=\frac{2}{\gamma -1}$
• B. $f=\frac{\gamma +1}{2}$
• C. $f=\frac{2}{\gamma +1}$
• D. $f=\frac{1}{\gamma +1}$

Answer 1

Answer: (A)

$\gamma =1+\frac{2}{f}$
where f is the degree of freedom
$\therefore \frac{2}{f}=\gamma -1$
or $f=\frac{2}{\gamma -1}.$
