Question

Calculate the uncertainty in the velocity of wagon og mass 300 kg whise

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

Have a gud day!!!!
