Smallest possible uncertainty in position of the electron moving with ...
Given, v = 3 × 107 m/s
Let    Δxmin be the minimum uncertainty in position of the electron and Δp the maximum uncertainty in the momentum of the electron.
Thus, we have,

= 0.03867 × 0.9949 × 10–10 m
= 3.8 × 10–12 m
The correct answer is: 3.8 × 10–12 m

Smallest possible uncertainty in position of the electron moving with ...
To determine the smallest possible uncertainty in the position of an electron moving with velocity 3 m/s, we can use the Heisenberg uncertainty principle.

According to the Heisenberg uncertainty principle, the product of the uncertainty in position and the uncertainty in momentum (mass times velocity) must be greater than or equal to Planck's constant (h) divided by 4π.

Δx * Δp ≥ h/4π

Since we know the velocity of the electron is 3 m/s, we can calculate the momentum using the equation:

p = m * v

where m is the mass of the electron (9.11 x 10^-31 kg) and v is the velocity (3 m/s).

p = (9.11 x 10^-31 kg) * (3 m/s)
p = 2.733 x 10^-30 kg·m/s

Now we can rearrange the uncertainty principle equation to solve for the uncertainty in position:

Δx ≥ (h/4π) / Δp

Δx ≥ (6.626 x 10^-34 J·s / (4π)) / (2.733 x 10^-30 kg·m/s)

Δx ≥ 6.06 x 10^-5 m

Therefore, the smallest possible uncertainty in the position of the electron moving with velocity 3 m/s is approximately 6.06 x 10^-5 meters.
