Mathematically,
Where,
(a)

Answer to Problem 1B.28E
The minimum uncertainty in the speed of an electron confined within a lead atom of diameter
Explanation of Solution
Given that, the uncertainty in position of an electron is
The uncertainty principle says that,
By plugging all data in the above equation, the value of uncertainty in the speed of electron can be calculated.
Therefore, the minimum uncertainty in the speed of an electron confined within a nanoparticle of diameter
