The measurement of the electron position...

The measurement of the electron position is associated with an uncertainty in momentum, which is equal to `1 xx 10^(-18)" g cm s"^(-1)`. The uncertainty in electron velocity is :
(Mass of an electron is `9 xx 10^(-28) g`)

A

`1 xx 10^(9) cm s^(-1)`

B

`1 xx 10^(6) cm s^(-1)`

C

`1 xx 10^(5) cm s^(-1)`

D

`1 xx 10^(11) m s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A

`Deltap = m Delta v`
`1 xx 10^(-18) g cm^(-1) = 9 xx 10^(-28)g xx Delta v`
`:. Delta v ~= 1 xx 10^(9) cm s^(-1)`
