Problem

The minimum uncertainty in the speed of an electron in a one-dimensional region of length 2a02a_0 (Where a0a_0 = Bohr radius 52.952.9 pm) is _____ km s−1\text{km s}^{-1}. (Given: Mass of electron =9.1×10−31= 9.1 \times 10^{-31} kg, Planck's constant h=6.63×10−34h = 6.63 \times 10^{-34} Js) [Main, July 29, 2022 (I)]
