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.

Suppose that the speed of an electron traveling 1.0 km/s is known to an accuracy of 1 part in 10,000 (that is, within 0.01%). What is the minimum uncertainty in the position of this electron? (m electron = 9.11 × 10-31 kg, h = 6.626 × 10-34 J • s) I think the answer is 1.2 mm but want to see if I did this correctly please show all work if handwritten please write clearly.

The mass of an electron is 9.11 x 10-31 kg and the diameter of a hydrogen atom is 100 pm (100 x 10-12 m). As the electron could be located anyway throughout the volume of the hydrogen atom, the maximum uncertainty in the position of the electron, Ax, can be estimated to be < 100 pm. Determine the minimum uncertainty in the speed of an electron in a hydrogen atom.
