Question

What is the minimum product of uncertainty in position and momentum of an electron

Answer 1

answer : h/4π

explanation : according to Heisenberg's uncertainty principle, it's impossible to determine simultaneously with high precision both the momentum and position of an electron.

in simple way, if we want to find out position and and momentum of electron simultaneously. then product of uncertainty in position and momentum must be at least h/4π.

i.e., ∆x × ∆P ≥ h/4π

hence , h/4π is the minimum product of uncertainty in the position and momentum of an electron.
