What will be the uncertainty in velocity of an electrons when the uncertainty in its positions is 1000 Å?

A

`5.79xx10^(2)ms^(-1)`

B

`5.79xx10^(8)ms^(-1)`

C

`5.79xx10^(4)ms^(-1)`

D

`5.79xx10^(-10)ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Deltax.mDeltav=h/(4pi)
Deltax=1000Å=1000xx10^(-10)mor10^(-7)m
Deltav= (6.626xx10^(-34)Js)/(4xx3.14xx9.1xx10^(-31)kgxx10^(-7)m)
=5.79xx10^(2)m//s`
