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 defiened.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A

C

A is true and R is false

D

Both A and R are false.

Text Solution

Verified by Experts

Assertion is true and reason is false.
According to Heisenberg's uncertainly principle the exact position and exact according to Heisnerberg's uncertainly principle, the exact position and exact momentum of an electron cannot be determined simultaneously . Thus, the path of electron in an atom is not clearly defind.
