Chemistry Question from JEE Main 2025 · 29 January, Shift 2

Given below are two statements:

Statement (I): It is impossible to specify simultaneously with arbitrary precision, the linear momentum and the position of a particle.

Statement (II): If the uncertainty in the measurement of position and uncertainty in measurement of momentum are equal for an electron, then the uncertainty in the measurement of velocity is hπ×12m\geq \sqrt{\frac{h}{\pi}} \times \frac{1}{2m}.

In the light of the above statements, choose the correct answer from the options given below:

  • A

    Statement I is true but Statement II is false.

  • B

    Both Statement I and Statement II are true.

  • C

    Statement I is false but Statement II is true.

  • D

    Both Statement I and Statement II are false.
