Question

Calculate the uncertainty in the position of a dust particle with mass equal to 1 mg if the uncertainty in its velocity is `5.5 xx 10^(-20) m s^(-1)`

Answer 1

Correct Answer - `9.55 xx 10^(-10) m`
`Delta x = (h)/(4pi m Delta v) = (6.6 xx 10^(-34) kg m^(2) s^(-1))/(4 xx 3.14 xx (1 xx 10^(-6) kh) xx (4.5 xx 10^(-20) ms^(-1))) = 9.55 xx 10^(-10) m`
