Expert Solution
Introduction:
We are given uncertainty in position of electron. We have to find uncertainty in momentum for this electron. We then find the kinetic energy of electron whose momentum is equal to this uncertainty.
The Heisenberg uncertainty principle is given as
Here are uncertainty in position and momentum respectively.
The minimum uncertainty is given as
