If the magnitude of uncertainties in position

(\Delta {x})

and momentum

(\Delta {p})

are equal then which of the following relation is correct?

View answer and explanation

Correct option: A

\Delta {v}=\frac{1}{{~m}} \sqrt{\frac{{h}}{4 \pi}}

Option A (

\Delta {v}=\frac{1}{{~m}} \sqrt{\frac{{h}}{4 \pi}}

) is correct because it correctly applies the Heisenberg uncertainty principle with equal uncertainties in position and momentum.
