The uncertainty in momentum of an electr...

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

A

`5.27xx10^(-30)` m

B

`1.05xx10^(-26)` m

C

`1.05xx10^(-28)` m

D

`5.25xx10^(-28)` m

Text Solution

Verified by Experts

`DeltaxxxDeltap=h/(4pi)`
(Heisenberg.s uncertainty principle)
`rArrDeltax=(6.62xx10^(-34))/(4xx3.14xx10^(-5))=5.27xx10^(-30)m`
