Question

calculate the uncertainity in position of particle mass=1mg and ∆v =5.5×10-20​

Answer 1

Answer:

Mass of dust particle= 1 x 10⁻³/1 x 10⁻³/1 = 10⁻⁶kg

change in velocity= 5.5 x 10⁻²⁰

h= 6.623 x 10⁻³⁴

x= 22/7

Δx⇒ mΔv= h/ 4π

Δx= h/ mΔv4π

= 6.623 x 10⁻³⁴ x 7/ 4 x 22 x 10⁻⁶ x 5.5 x 10⁻²⁰

Δx= 9.58 x 10⁻¹⁰ m
