Answer» ONG>ANSWER: Hi friend Hope this answer helps you Explanation: The uncertainty in position is EQUAL to de Broglie wavelength. ⟹Δx=λ= mv h
....... (1) The HEISENBERG's uncertainty principle is ΔxΔv≥ 4πm h
...... (2) From equations (1) and (2), ( mv h
Δv≥ 4πm h
) Thus, v Δv
≥ 4π 1
Hence, minimum percentage error = v Δv
×100= 4π 100
=7.96≈8. |
