Concept explainers
The lowest possible energy.
Answer to Problem 11P
The answer is
Explanation of Solution
Given info: Radius,
Mass of an electron
Formula used:
It is known that
Where,
Calculation:
Use the radius as the uncertainty in position for the electron.
Now calculate the uncertainty in momentum by using the formula
Suppose that the lowest value for the momentum is the least uncertainty. So, calculate the lowest possible energy by using the formula
Expand the equation
Where,
Substitute all the known and given values in equation
Conclusion:
The required value is
