1.	The uncertainty of a ball is given by 0.5A°. Then calculate the uncertainty in momentum.(a) 2.055 x 10^-24 kgm/s(b) 1.015 x 10^-24 kgm/s(c) 1.055 x 10^-24 kgm/s(d) 1.095 x 10^-24 kgm/sThe question was posed to me during an online interview.The doubt is from Towards Quantum Mechanical Model of the Atom topic in portion Structure of Atom of Chemistry – Class 11
Answer» Correct option is (C) 1.055 x 10^-24 kgm/s Best explanation: Heisenberg’s PRINCIPLE of uncertainty states that Δx. Δp ≥ h/4π, x is position, p is momentum and “h” is the Planck’s constant and is EQUAL to 6.626 x 10^-34 JS. Relative momentum Δp = h/4πΔx = 1.055 x 10^-24 kgm/s.
