Answer:
[tex]\Delta v = 0.123 m/s[/tex]
Explanation:
As per the law of uncertainty we know that
[tex]\Delta p \times \Delta x = \frac{h}{4\pi}[/tex]
now we know that
[tex]\Delta x = 0.70 nm[/tex]
[tex]m = 6.10 \times 10^{-25}[/tex]
also we have
[tex]h = 6.626 \times 10^{-34} J.s[/tex]
now we will have
[tex]m\Delta v \times \Delta x = \frac{h}{4\pi}[/tex]
[tex](6.10 \times 10^{-25})\Delta v \times (0.70 \times 10^{-9}) = \frac{6.626 \times 10^{-34}}{4\pi}[/tex]
[tex]\Delta v= 0.123 m/s[/tex]
