MCQ
What will be the mass of a particle if uncertainty in its position is $10^{-8}\, m$ and uncertainty in velocity is $5.26 \times 10^{-25}\, m\, s^{-1}$ ? ............... $\mathrm{kg}$
- ✓$0.01$
- B$100$
- C$1$
- D$10$
$\mathrm{m}=\frac{\mathrm{h}}{4 \pi \Delta \mathrm{x} \Delta \mathrm{v}}$
$=\frac{6.62 \times 10^{-34}}{4 \times 3.14 \times 10^{-8} \times 5.28 \times 10^{-25}}$
$=0.099 \times 10^{-1}$
$=0.01\, \mathrm{kg}$
