Question

Calculate the uncertainty in the velocity of a wagon of mass 2000 kg

Answer 1

Given data:

Mass of wagon (m) =2000 kg

Position (Δx)= 10 pm = 10 ×10^-12m = 10^-11m .

Planck's constant = 6.63 x10^-34 Js Βy uncertainty principle,

∆v = h/ 4π (m∆x)

= 6.626 X10^-34 / 4 x 3.14 (2000 x 10^ -11)

=2.636 x 10^-39 m/s
