Aproton is confined to a space 1 fm wide (about the size of an atomic nucleus). what's the minimum uncertainty in its velocity?

Minimum uncertainty in velocity of a proton,      

Explanation:

It is given that,

A proton is confined to a space 1 fm wide,

We need to find the minimum uncertainty in its velocity. We know that the Heisenberg Uncertainty principle gives the uncertainty between position and the momentum such that,

Since, p = mv

So, the minimum uncertainty in its velocity is greater than . Hence, this is the required solution.
