Explanation / Answer

use Heisenberg uncertainty principle,

deltax*deltav >= h/(4*pi*m)

Here:

deltav = 3.03*10^5 m/s

mass, m = 9.11*10^-31 Kg

Putting values,

deltax*(3.03*10^5) >= (6.626*10^-34)/(4*3.14*9.11*10^-31)

deltax*(3.03*10^5) >= 5.791*10^-5

deltax > 1.91*10^-10 m

Answer: 1.91*10^-10 m
