If the uncertainty in the position of proton is `6xx10^-8m`, then the minimum uncertainty in its speed is

A

`1cms^(-1)`

B

`1 ms^(-1)`

C

`1 mms^(-1)`

D

`100 ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
2
`Deltap=mDeltav=(h)/(Deltax)or`
`Deltav=(h)/(mDeltax)=(1.034xx10^(-34))/(1.67xx10^(-27)xx6xx10^(-8))=1ms^(-1)`
