Answer:
Explanation:
According to Heisenberg's uncertainty principle ,
where , Δ x = Uncertainty in position
m = mass
Δ v = change in velocity
h = planck's constant
We have Δ x = 10⁻¹
m = 0.25 g = 0.25 × 10⁻³ kg
We have h = 6.626 × 10⁻³⁴ J sec.
We have to find Δ v
Put the value in formula we get
Thus , we get answer .
