Question : 61
Total: 67
If the position of the electron is measured within an accuracy of ± 0.002 nm, calculate the uncertainty in the momentum of the electron. Suppose the momentum of the electron is
Solution:
According to uncertainty principle, Δx Δp =
where, Δx = ± 0.002 nm = ± 0.002 ×10 – 9 m
10 − 23 k g m ∕ s e c
Actual momentum =
.
10 − 24 k g m ∕ s
This value cannot be defined as the actual magnitude of the momentum is smaller than the uncertainty in momentum, which is impossible.
where, Δx = ± 0.002 nm = ± 0.002 ×
Actual momentum =
