**1. Question**

The speed of an electron is known to be between 6.0×10^6 m/s and 6.7×10^6 m/s . Estimate the uncertainty in its position.

## Homework Equations

ΔpΔx ≥ h/2π

(mΔv) Δx ≥ h/2π (Since Δp= mΔv)

Δx≥ h/2π(mΔv)

h= 6.63*10

^{-34}J*s

c= 3.0*10

^{8}

mass of electron= 9.11*10

^{-31}

## The Attempt at a Solution

(6.63*10^-34)/(2pi(9.11*10^-31)*(6.7*10^6 - (6*10^6))

= 0.00000000016546 m

Apparently this is incorrect. What am I doing wrong?
