Uncertainty in position of electron is 1...

Uncertainty in position of electron is `10^(-10)` m. uncertainty in its momentum will be…….`kgms^(-1).(h=6.62xx10^(-34) J-s)`

A

`1.05 xx 10^(-24)`

B

`1.03 xx 10^(-24)`

C

`1.06 xx 10^(-24)`

D

`1.08 xx 10^(-24)`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaxDeltaP ge (h)/(2pi)`
`implies DeltaP ge (6.62 xx 10^(-34))/(2 xx 3.14 xx 10^(-10))`
`DeltaP ge 1.05 xx 10^(-24) = 1.0536 xx 10^(-24)`
