A non relativistic proton is confined to a length of 2.0 pm on the x-axis. What is the kinetic energy of the proton if its speed is equal to the minimum uncertainty possible in its speed? (1 eV = 1.60 × 10-19 J, h= 1.055 × 10-34 J ? s, m proton = 1.67 × 10-27 kg) 1) 0.13 eV 2) 1.3 eV 3) 13 eV 4) 130 eV 5) 1300 eV
An electron with a kinetic energy of 47.34 eV is incident on a square barrier with Ub = 56.43 eV and w = 2.000 nm. What is the probability that the electron tunnels through the barrier? (Use 6.626 ✕ 10−34 J · s for h, 9.109 ✕ 10−31 kg for the mass of an electron, and 1.60 ✕ 10−19 C for the charge of an electron.)
A proton (mass = 1.67 × 10−27 kg) has a kinetic energy of 0.8 MeV. If its momentum is measured with an uncertainty of 1.29%, what is the minimum uncertainty in its position? (h = 6.63 × 10−34 J⋅s and 1 eV = 1.6 × 10−19 J)
