Isotopes differ by the number of nucleons but have the same number of protons. Ok, I'm starting to see it.
So, why do you subtract the nucleon atomic mass from the atomic mass difference? Isn't the difference in mass between two different isotopes already there? Or is it asking for the...

Homework Statement
Two point charges are fixed on the y axis: a negative point charge q1 = -28 µC at y1 = +0.25 m and a positive point charge q2 at y2 = +0.38 m. A third point charge q = +8.5 µC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two...
mgh = 1/2mv^2 + 1/2IW^2
Tangent Velocity = rW
W=Tangent V / r
Substitute W and solve for h.
h = (1/2V^2 + 1/3(Tangent V)^2) / g
Tangent V = translational V
h=3.18
I got it now, Thanks!
