A particle with mass m=6.6×10−27 kgm = 6.6 \times 10^{-27} \text{ kg} (approximately the mass of a lithium nucleus) is moving with speed v=1.2×106 m/sv = 1.2 \times 10^6 \text{ m/s}. According to the Heisenberg uncertainty principle, if the momentum is known to within Δp=1.0%\Delta p = 1.0\% of its value, what is the minimum uncertainty in the particle's position?
