A dust particle has mass equal to

10^{-11} \mathrm{~g}

, diameter

10^{-4} \mathrm{~cm}

and velocity

10^{-4} \mathrm{~cm} \mathrm{~s}^{-1}

. The error in measurement of velocity is

0.1 \%

. What will be the uncertainty in its position?

View answer and explanation

Correct option: D

0.527 \times 10^{-9} \mathrm{~cm}

Answer D (0.527 x 10-9 cm) is correct because it is calculated using the Heisenberg uncertainty principle, considering the error in velocity measurement.
