# [OS X TeX] Asymmetric size in eqnarray

The following produces a pair of equations in the same line, each of
which have fractions.  But the fractions in the two equations are of
different size.  How do I force the fractions to have the same size and
improve the appearance of the output?

Thanks

\begin{eqnarray}
&j_N=\sqrt{\frac{N}{2}(\frac{N}{2}+1)} \hspace{0.5cm}
&j_M=\sqrt{\frac{M}{2}\left(\frac{M}{2}+1\right)}\\
&m=\frac{N-M}{2} &J=\sqrt{|m|(|m|+1)}
\end{eqnarray}
