Hi Chroot
Just seen your post, thank you for replying. I think I may have it now, but for clarities sake I'll write the first bit of the question I have been trying to solve.
A hydrogen nucleus and a nucleus of an 'unknown' atom are stationary, 5.0 x 10E-10 apart. The mass of the hydrogen...
Ok, and the answer is...
Right, here goes.
Rearranging coulomb's equation we get (with help from Locrian)
q2 = (Fe x r squared)/Ke x q1
Substituting known values into the equation gives:
q2 = (5.5 x 10 E-9) x (5.0 x 10 E-10)2 / (8.99 x 10E9) x (1.6 x 10E-19) =
9.6 x 10E-19 C
Hi Locrian
thanks for your reply. I'm not susprised you didn't understand some of my post I was mightily confused! I have tried again to rearrange the equation now you have steered me right to what it should be, (I did get this previously but wasn't sure if it was correct)so I shall...
have been trying this for 8 hours. have finally come up with q = Fe X r squared, divided by Ke.
In the problem I have been told the value for:
Fe = 5.5 x 10-9, r = 5.0 x 10 -10 and of course Ke (8.99 x 10 9)
known nucleus charge is e= 1.6 x 10-19.
I have been asked whether the magnitude of...
