Uncertainty in position of a 0.25 kg particle is `10^(-5)` , uncertainty of velocity is `(h=6.6xx10^(-34) Js)`

A

`1.2xx10^(34)` m/sec

B

`2.1xx10^(-29)` m/sec

C

`1.6xx10^(-20)` m/sec

D

`1.7xx10^(-9)` m/sec

Text Solution

Verified by Experts

The correct Answer is:
B
According to `Deltax xxmxxDeltav=h/(4pi),Deltav=h/(Deltaxxmxx4pi)`
`=(6.6xx10^(-34))/(10^(-5)xx0.25xx3.14 xx4)=2.1 xx10^(-29)m//s`
