Question

Be sure to answer all parts.

Calculate the minimum uncertainty in the momentum of an object for which the uncertainty in position is

5 Å.

Enter your answer in scientific notation.

To what minimum uncertainty in velocity does this correspond if the particle is a neutron

(mass 1.0087 amu)?

To what minimum uncertainty in velocity does this correspond if the particle is an electron

(mass 5.486 × 10⁻⁴ amu)?

Answer 1

According to Heisenberg uncertainty principle,
Uncertainty in position of object,
Planks constant,
Uncertainty in the momentum of object,
Uncertainty in the momentum of neutron,
Mass of the the neutron,
Uncertainty in the momentum of neutron,
Uncertainty in velocity of neutron ,
Uncertainty in the momentum of electron,
Mass of the the electron ,
Uncertainty in the momentum of electron,
Uncertainty in velocity of electron ,
= 1.06 x 10-25 Kg. m/s / 9.11 x 10-31 Kg
= 1.16 x 105 m/s
