Question

Assertion :The position of electron can be determined with the help of an electronic microscope. Reason: The product of uncertainty in momentum and the uncertainty in the position of an electron cannot be less than a finite limit.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is D Assertion is incorrect but Reason is correct

^{Heisenberg's uncertainty principle states that the more precisely the position of some particle is determined, the less precisely its momentum can be known, and vice versa.}

^{$\Delta x\times \Delta p\ge \frac{h}{4\pi }$}

^{where, $\Delta x=$ uncertainty in position and $\Delta p=$ uncertainty in momentum.}
