Atomic Structure Question 509

Question: Uncertainty in position of a 0.25 g particle is 105 . Uncertainty of velocity is (h=6.6×1034,Js) [AIEEE 2002]

Options:

A) 1.2×1034

B) 2.1×1029

C) 1.6×1020

D) 1.7×109

Show Answer

Answer:

Correct Answer: B

Solution:

According to Δx ×m ×Δv=h4π ; Δv=hΔx ×m ×4π

=6.6×1034105×0.25×3.14×4=2.1×1029  m/s
