If the position of the electron is measured within an accuracy of +- 0.002 nm. Calculate the uncertainty in the momentum of the electron. Suppose the momentum of the electron is h//4pi_(m)xx0.05 nm, is there any problem in defining this value.

According to de Broglie’s expression,
lambda = (h)/(mv)
Substituting the values in the expression,
lambda = (6.626 xx 10^(-34) Js)/((0.1 kg)(4.37 xx 10^(5) ms^(-1)))
lambda = 1.516 xx 10^(-38) m
