Question

Calculatethe uncertainity in the velocity of a wagon of mass 3000kg shose uncertainity in position is knwn to be 10pm

Answer 1

Given data:

Mass of wagon (m) = 3000 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 / 4x3.14 (3000 x 10^-11)

= 1.76 X 10^-27 m/s
