What will be the uncertainty in velocity of an electrons when the uncertainty in its positions is $1000 Å$ ?

Options:

Answer:

Solution:

$Δ x . m Δ v = \frac{h}{4 π}$
$1000 Å = 1000 \times 1 0^{- 10} m$
or $1 0^{- 7} m$
$Δ v = \frac{6.626 \times 1 0^{- 34} J s}{4 \times 3.14 \times 9 \times 1 0^{- 31} k g \times 1 0^{- 7} m}$
$5 .79 × 10^{2} {ms}^{- 1}$
