1.0 \times {10^{ - 5}}\mathrm{kg\;m}{\mathrm{s}^{ - 1}}

, The uncertainty in its position will be

View answer and explanation

Correct option: C

5.27 \times {10^{ - 30}}\mathrm{m}

Option C (

5.27 \times {10^{ - 30}}\mathrm{m}

) is correct because it is calculated using the Heisenberg uncertainty principle.
