The uncertainty in the velocity of moving bullet of mass 10 g, when uncertainty in its position is `10^(-5)` m is

A

`5.2xx10^(-28)m//s`

B

`5.2xx10^(-22)m//s`

C

`3xx10^(-28) m//s`

D

`3xx10^(-22)m//s`

Text Solution

Verified by Experts

The correct Answer is:
A
`Deltax.Deltap=h/(4pi)or DeltaxmDeltav=h/(4pi)`
`Deltav=h/(4piDeltaxm)=((6.626xx10^(-34))js)/(4xx3.14xx10^(-5)mxx10^(-2)kg)`
`=5.2xx10^(-28)m//s`
