Uncertainty in position of a particle of 25 g in space is 10-5 m. Hence uncertainty in velocity (ms-1) is (Planck's constant h = 6.6 × 10-34 Js)                                                            [AIEEE- 2002]
  • a)
    2.1 × 10-28
  • b)
    2.1 × 10-34 
  • c)
    0.5 × 10-34
  • d)
    5.0 × 20-24
Correct answer is option 'A'. Can you explain this answer?

Uncertainty in position of a particle of 25 g in space is 10-5m. Hence...
∆p×∆x = h/4π
Or ∆v = h/4π∆xm      (since p = mv)
=6.6×10-34Js/4×3.14×25×10-3kg ×10-5 
by solving this your answer is 2.1×10-28
