Hiesenberg.s uricertainty principle states that it is impossible to determine simultaneously the position and momentum of a particle. He considered the limits of how precisely we can measure properties of an `e^-` (or)other microscopic particles like electron. The more accurately we measure the momentum of a particle, less accurately we can determine its position.
The police are monitoring an automobile of mass 2.0 tons speeding along a high way. They are certain about location of the vehicle only to with in Im, what is the minimum uncertainty in the speed of the vehicle ?

Options

A. `3.9xx10^(-38) ms^(-1)`
B. `12.4xx10^(-38) ms^(-1)`
C. `2.63xx10^(-38) ms^(-1)`
D. `0.62xx10^(-38) ms^(-1)`

Answer

C

Explanation

`Deltav =(h)/(4pi . ""m Delta )`
`=(6.625xx10(-34))/(4xx3.14xx2000xx1)` `=2.63xx10^(-38)` m/sec
