What will be the mass of a particle if uncertainty in its position is `10^(-8)` m and velocity is `5.26xx10^(-25)ms^(-1)`?

A

0.01 kg

B

0.1 kg

C

1 kg

D

10 kg

Text Solution

Verified by Experts

The correct Answer is:
A
`Deltax.mDeltav=h/(4pi)
10^(-8)mxxmxx5.26xx10^(-25)ms^(-1)=(6.626xx10^(-34)Js)/(4xx3.14)
m=(6.626xx10^(-34)Js)/(4xx3.14xx10^(-8)mxx5.26xx10^(-25)ms^(-1))=0.01kg`
