Question

An electron has a speed of 300 m/s accurate to 0.01%.
With what fundamental accuracy can we locate the position of the electron

anonymous · Answer

Use Heisenberg Uncertainty principle.

@@ardalan deltax=h/mdeltaV ..... 

how r we gonna substitute ....

anonymous · Answer

use the mass of electron.

anonymous · Answer

can u pl give the formula.... mass is not given ..rt ....

anonymous · Answer

the mass of electron is :9.10938291 × 10-31 kilograms
Planck's constant =
6.62606957 × 10-34 m2 kg / s

you have delta V. then you will find delta x.

anonymous · Answer

kk well h is the planks constant ... them m remains ....deltaV=300    h=
6.62606957 × 10^-34 m2 kg / s  whats m =?

anonymous · Answer

m is the mass of the particle. here is the mass of electron that i gave you in my last post. :)
