If uncertainities in measurement of position and momentum of an electron are equal, then the uncertainity in measurement of its velocity is $x \times 1 0^{12}$ . The value of x (the closest whole number value) is
$m_{e} = 9.1 \times 1 0^{- 31} kg$ , and $h = 6.625 \times 1 0^{- 34} Js$ .

Heisenberg's Uncertainty Principle: Δ x Δ p ≥ 4 π h ​ . Given Δ x = Δ p , Δ v = 4 π m e 2 ​ h ​ ​ = 8 × 1 0 12 m/s. So, x = 8.
