The uncertainty in the momentum of an electron is `1.0xx10^(-5)kgms^(-1)`. The uncertainty in position will be `(h=6.6xx10^(-34)kgm^(2)s^(-1))`

A

`5.25xx10^(-28)m`

B

`1.05xx10^(-26)m`

C

`5.25xx10^(-30)m`

D

`1.05xx10^(-28)m`

Text Solution

Verified by Experts

The correct Answer is:
A
`Deltax xx Deltap=h/(4pi)`
`Delta x=h/(4pixx Deltap)=(6.6xx10^(-34))/(4xx2/7xx1xx10^(-5))`
`=5.25xx10^(-30)m`
