Concept explainers
The uncertainty in the electron’s position.
Answer to Problem 12P
The answer is
Explanation of Solution
Given info: Kinetic energy,
Energy increased by
Formula used:
It is known that
Where,
Calculation:
First calculate the momentum of electron by using the formula
Substitute the given and known values in
Now, when the energy is increased by
So, the uncertainty in momentum will be
Substitute the calculated values in equation
Now, calculate the uncertainty in the electron’s position by using the formula
Conclusion:
The required value is
