Question

The uncertainty in the position of a moving bullet of mass 0.02kg is 5×10^-6m.calculate the uncertainty in its velocity​

Answer 1

Answer:

According to Heisenberg's uncertainty principle,

Δx⋅mΔv=  

4π

h

​  

 

or m=  

4πΔx⋅Δv

h

​  

 

      =  

4×3.143×10  

−10

×5.27×10  

−24

 

6.625×10  

−34

 

​  

 

      =0.099kg.
