Per NCERT eqn 2.23, Heisenberg's uncertainty principle (1927) states which inequality between uncertainty in position Δx and momentum Δp_x?
AΔx · Δp_x ≥ h / (4π)
BΔx · Δp_x = 0
CΔx + Δp_x = 0
DΔx · Δp_x ≤ h / (4π)
Answer & Solution
Correct answer: A. Δx · Δp_x ≥ h / (4π)
Per NCERT eqn 2.23, Δx · Δp_x ≥ h/(4π). One cannot simultaneously know exact position + exact momentum.
