Question

Δx. Δp ≥ h/4π.

(a) True

(b) False

I have been asked this question in a national level competition.

Question is from Towards Quantum Mechanical Model of the Atom in division Structure of Atom of Chemistry – Class 11

Answer 1

The correct choice is (a) True

To elaborate: Heisenberg’s principle of uncertainty states that the product of relative momentum and velocities is equal to greater than the h/4π, where is “h” is the Planck’s constant and is equal to 6.626 x 10^-34 Js. Hence the above statement is true.
