The uncertainty in momentum of an electron is `1 xx 10^-5 kg m//s`. The uncertainty in its position will be `(h = 6.62 xx 10^-34 kg m^2//s)`.

A

`1.05xx10^(-28)m`

B

`1.05xx10^(-26)m`

C

`5.27xx10^(-30)m`

D

`5.25xx10^(-28)m`

Text Solution

Verified by Experts

The correct Answer is:
C
According to `DeltachixxDeltap=h/(4pi)`
`Deltachi=h/(Deltapxx4pi)=(6.62xx10^(-34))/(1xx10^(-5)xx4xx3.14)=5.27xx10^(-30)m`.
