The measurement of the electron position is associated with an uncertainty in momentum, which is equal to $1 \times {10^{ - 18}}\;{\rm{g\;cm\;}}{{\rm{s}}^{ - 1}}.$. The uncertainty in electron velocity is: (mass of an electron is$9 \times {10^{ - 28}}\;{\rm{g}}$)

$1.1 \times {10^9}{\rm{cm\;}}{{\rm{s}}^{ - 1}}$

$1 \times {10^6}{\rm{cm\;}}{{\rm{s}}^{ - 1}}$

$1 \times {10^5}{\rm{cm\;}}{{\rm{s}}^{ - 1}}$

$1 \times {10^{11}}{\rm{cm\;}}{{\rm{s}}^{ - 1}}$

The measurement of the electron position is associated with an uncertainty in momentum, which is equal to

1 \times {10^{ - 18}}\;\mathrm{g\;cm\;}{\mathrm{s}^{ - 1}}.

. The uncertainty in electron velocity is: (mass of an electron is

9 \times {10^{ - 28}}\;\mathrm{g}

)

View answer and explanation

Correct option: D

1.1 \times {10^9}\mathrm{cm\;}{\mathrm{s}^{ - 1}}

Option D (

1.1 \times {10^9}\mathrm{cm\;}{\mathrm{s}^{ - 1}}

) is correct because it is calculated using the formula Δv = Δp/m.
