Assertion (A): It is impossible to determine the exact position and exact momentum of an electron simultaneously. Reason (R): The path of an electron in an atom is clearly defined.
0.Both A and R are correct and R is the correct explanation of A.
1.Both A and R are correct but R is NOT the correct explanation of A.
2.A is correct but R is incorrect.
3.R is correct but A is incorrect.
Explanation
Assertion (Heisenberg's uncertainty principle) is correct. Reason is incorrect — the path of an electron in an atom is NOT clearly defined; electrons exist as probability distributions (orbitals).
