Achieve #18

[lilyhoke 2E]

I have been working at problem 18 of the achieve homework, but keep getting wrong answers. I understand we need to use the Heisenberg equation, but I don't feel confident in applying it. Could someone walk me through the steps they took in solving this?

Hi! In order to solve it, I just plugged in all of the values that were given to us. I used Planck's constant, delta v, and the mass of an electron (plus 4 pi). Thats how I got my answer at least!

Hope this helps!

Hi!

In more details it would the formula provided delta >- h/4pimdeltav (the equation is stated in the problem)

Now, we now that h is Planck's constant = 6.62608*10^34J.s
pi = 3.14
delta v (is given)= 0.01*10^6 m/s
mass of an electron (since this is a problem about the position of an electron, also remains the same throughout all problems) = 9.11*10^-31kg

Now, since we have all the data needed, we can just input it into the formula which would look like:

delta x >- (6.626*10^-34kg.m^2/s) /(4(3.14)(9.11*10^-31kg)(0.01*10^6m/s))

which is about 5.79*10^-9m

Hope this clarifies more the steps!
