The uncertainty in the position of an electron along an x axis is given as 68 pm. What is the least uncertainty in any simultaneous measurement of the momentum component px of this electron?

Explanation:

Given that,

The uncertainty in the position of an electron along the x-axis is,

We need to find the east uncertainty in any simultaneous measurement of the momentum component of this electron.

We know that the Heisenberg's uncertainty principle gives the relation between the uncertainty in position and the momentum of electron as :

Putting all the values, we get :

So, the momentum component of this electrons is greater than .
