Question

Calculate the uncertainty in the position of an electron if the uncertainty in its velocity is  5.7 x 10 5 m/s. Given mass of electron= 9.1 x 10 -31 kg​

Answer 1

Answer:

By Heisenberg's Uncertainty principle,

Δx×Δp≥  

4π

h

​  

 

Position of both an electron & a helium atom =1 nm

Momentum of an electron =5×10  

−25

 kg.m/s

When the postion of both the electron and helium atom is same then the momentum of helium atom is equal to momentum of an electron.

Momentum of Helium atom =5×10  

−26

 Kg.m/s.
