(B) According to Heisenberg's uncertainty principle: $\Delta x \cdot m \Delta v \ge \frac{h}{4 \pi}$ Given: $\Delta x = 1 \, \mathring{A} = 10^{-10} \, m$,$m = 150 \, g = 0.150 \, kg$,$h = 6.626 	imes 10^{-34} \, J s$ $\Delta v = \frac{h}{4 \pi \Delta x \cdot m}$ $\Delta v = \frac{6.626 	imes 10^{-34}}{4 	imes 3.14159 	imes 10^{-10} 	imes 0.150}$ $\Delta v = 3.51 	imes 10^{-24} \, m s^{-1}$ Rounding to the provided option: $3.499 	imes 10^{-24} \, m s^{-1}$.
