Question

A microscope using suitable photons is employed to locate an electron in an atom with in a distance of 0.1A. what is the uncertainity involved in the measurment of its velocity

Answer 1

Answer:

ΔV ≥ 5.79 ×10^6  ms  −1

Explanation:

According to Heisenberg’s Uncertainty principle:

del X . del P >= h / 2pi

Now,

m=9.11×10^−31 kg

h=6.626×10^ −34 Js

So..,

ΔV≥  4π.m.Δx. h

​  

ΔV≥  4×3.14×9.11×10  −31 ×0.1×10  −10

 6.626×10  −34

= ΔV≥0.579×10  7 ms  −1

 

ΔV≥5.79×10  6 ms  −1
