Answer» `1mms^(-1)` Uncertainty in momentum `Deltap=(h)/(2piDeltax)` `THEREFORE Deltap=(6.625xx10^(-34))/(2xx3.14xx6xx10^(-8))` `therefore Deltap=0.1758xx10^(-26)` `therefore mDeltav=0.1758xx10^(-26)` `therefore Deltap=(0.1758xx10^(-26))/(m)` `=(0,1758xx10^(-26))/(1.67xx10^(-27))=0.105269xx10^(1)` Uncertainty in velocity `therefore Deltav~~1.0 ms^(-1)` |
