Uncertainty Principle Using Momentum and Position: The radius of a typical nucleus is about 5 × 10-15 m. Assuming this to be the uncertainty in the position of a proton in the nucleus, estimate the uncertainty in the proton's energy, in MeV. (mproton = 1.67 × 10-27 kg, h = 6.626 × 10-34 J ? s, 1 eV = 1.6 × 10-19 J)
A. 0.4 MeV
B. 0.6 MeV
C. 0.8 MeV
D. 1.0 MeV
Answer: C

A proton (mass = 1.67 × 10^-27 kg, charge = 1.60 × 10^-19 C) moves from point A to point B under the influence of an electrostatic force only. At point A the proton moves with a speed of 60 km/s. At point B the speed of the proton is 80 km/s. Determine the potential difference VB - VA
