Calculate uncertainty in the momentum of electron if uncertainty in its position is 10-10 m.
Calculate uncertainty in the momentum of electron if uncertainty in its position is $10^{-10}$ m. [5]
- Uncertainty in position: $\Delta x = 10^{-10}$ m - Planck's constant: $h = 6.626 \times 10^{-34}$ J·s - (Mass of electron $me = 9.11 \times 10^{-31}$ kg is available but not required for momentum uncertainty) --- $$\Delta x \cdot \Delta p \geq \frac{h}{4\pi}$$ For numerical calculations at the ...
