JEE Mains · Chemistry · STD 11 - 2. structure of atom

Given below are two statements :
Statement (I) : It is impossible to specify simultaneously with arbitrary precision, both 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 \(\geqslant \sqrt{\frac{\mathrm{h}}{\pi}} \times \frac{1}{2 \mathrm{~m}}\).
In the light of the above statements, choose the correct answer from the options given below :

  1. A Statement I is false but Statement II is true
  2. B Both Statement I and Statement II are false
  3. C Both Statement I and Statement II are true
  4. D Statement I is true but Statement II is false
Verified Solution

Answer & Solution

Correct Answer

(C) Both Statement I and Statement II are true

Step-by-step Solution

Detailed explanation

According to Heisenberg's uncertainty principle, it is impossible to determine simultaneously the exact position and momentum of particle like electron. If…
