Vedclass · Answer

(B) According to Heisenberg's uncertainty principle,$\Delta x \cdot \Delta v \geq \frac{h}{4 \pi m}$.Given: $\Delta x = 10.98 \ nm = 10.98 	imes 10^{-9} \ m$,$m = 9.11 	imes 10^{-31} \ kg$,$h = 6.63 	imes 10^{-34} \ Js$.Substituting the values:$\Delta v = \frac{h}{4 \pi m \Delta x} = \frac{6.63 	imes 10^{-34}}{4 	imes \pi 	imes 9.11 	imes 10^{-31} 	imes 10.98 	imes 10^{-9}}$.$\Delta v = \frac{6.63 	imes 10^{-34}}{4 	imes \pi 	imes 10.00278 	imes 10^{-39}}$.$\Delta v = \frac{6.63 	imes 10^5}{4 	imes \pi 	imes 10.00278} = \frac{1.6565 	imes 10^4}{\pi} \ ms^{-1}$.
