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 :
- A Statement I is false but Statement II is true
- B Both Statement I and Statement II are false
- C Both Statement I and Statement II are true
- D Statement I is true but Statement II is false
Answer & Solution
Correct Answer
(C) Both Statement I and Statement II are true
Step-by-step Solution
