Calculate the wavelength associated with a 20Ne+ ion moving at a velocity of 2.0 × 105 m/s. The atomic mass of Ne-20 is 19.992 amu (1 amu = 1.66 × 10-24 g and h = 6.63 × 10-34 J s).A) 1.0 × 10-13 mB) 1.0 × 10-16 mC) 1.0 × 10-18 mD) 9.7 × 1012 mE) 2.0 × 10-13 cmand then, According to the Heisenberg uncertainty principle, if the uncertainty in the speed of an electron is 3.5 × 103 m/s, the uncertainty in its position (in m) is at least (mass electron = 9.109 × 10-28 g):A) 1.7 × 10-8 mB) 6.6 × 10-8 mC) 17 mD) 66 mE) None of the choices is correct.
