### 1. 44

What is the minimum uncertainty in the position of a hydrogen atom in a particle accelerator given that its speed is known to within 5.0 ms1?

Would you take the weight of hydrogen atom from its atomic mass in kilograms?

$\Delta x\Delta p\geq h/(4\pi )$ and $\Delta p=m\Delta v$

Delta v= 5.0 m/s and the mass of a hydrogen atom is (1.0079x10^-3)/(6.022x10^23) kg/atom
