Which among the following is a correct statement based on Heisenberg's uncertainty principle?
) It is impossible to detemine exact position and exact momentum of an electron simultaneously.
) It is applicable to even macroscopic objects.
) It is possible to detemine the exact position and momentum of an electron simultaneously.
) It is impossible to determine the exact position and momentum of macroscopic object simultaneously.
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
According to Heisenberg uncertainty principle, the very concepts of exact position and exact velocity together, in fact, have no meaning in nature. The uncertainties implied by this principle for ordinary objects are too small to be observed.
