If uncertainty in position and momentum are equal, then uncertainty in velocity is:

1.  $\frac{1}{2\mathrm{m}}\sqrt{\frac{\mathrm{h}}{\mathrm{\pi }}}$

2.  $\sqrt{\frac{\mathrm{h}}{2\mathrm{\pi }}}$

3.  $\frac{1}{\mathrm{m}}\sqrt{\frac{\mathrm{h}}{\mathrm{\pi }}}$

4.  $\sqrt{\frac{\mathrm{h}}{\mathrm{\pi }}}$
