Table-tennis ball has mass 10g and s peed of 90m/s. if speed can be meausred within an accuracy of 4%. What will be the uncertainly in speed and position?

A

`10,4xx10^(-33)`

B

`10,5.27xx10^(-34)`

C

`0.1,5xx10^(-34)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Uncertainty in the speed of ball `=(100xx10)/100=10m//s
Deltax.mDeltav=h/(4pi)`
Uncertainty in the position,
`Deltax=h/(4pimDeltav)=(6.626xx10^(-34))/(4xx3.14xx10xx10^(-3)xx10)=5.27xx10^(-34)m`
