An electron has a momentum p≈ 1.7×10−25 kg⋅m/s. What is the minimum uncertainty in its position that will keep the relative uncertainty in its momentum (Δp/p) below 2.0%? Place final answer in 2 significant figures and convert answer to nanometers. The answer is NOT 15nm or 16nm from: x = h / [(4pi)(2%)(p)] = (6.626×10−34) / [(4pi)*(0.02)(1.7x10−25)]) = 15.5nm. Do not write this as the answer.
