Heisenberg's uncertainty principle can be expressed mathematically as Δx*Δp = h/4π, where Δx and Δp denote the uncertainty in position and momentum respectively and h is Planck's constant. What would be the uncertaintry in the position of a neutron (mass = 1.675e-27 kg) that was traveling at a velocity of 1.308e+4 m/s if the velocity has an uncertainty of 1.398%?

Answer 1

delta x = solve
delta p = mass*velocity
You know h and 4*pi
Multiply velocity by +/- 0.01398 and solve for delta x.
