For 1, right. I think their way of drawing that imaginary horizontal line is a little weird. But your elaboration makes perfect sense. So I have another question now regarding anharmonic oscillators: It seems that when R goes to infinity this graph will become asymptotic. Is the limit of this...
Hey all, I want to preface this with I wasn't sure if I should put this in the physics thread since it is quantum mechanics or in chemistry thread since this is for my Physical Chemistry course. I will gladly move the thread if the community feels it is more appropriate in the physics thread. I...
Ok, sorry I had a spark of genius. And I've been kind of going with it. I just want to know if I'm on the right track. I set the +q1 charges equal to each other and got:
r=.11/(V1-V2)
Then I set the -q2 charges equal to each other and got:
.035V1=.0765V2
Substitute to get
r=.11/(V1-.035V1)...
See that's the thing, i'm still iffy on the relationshiphs. My best educated guess would be:
Since V @ .0335m is equal to zero. That would mean the net electric field at that point is also 0 because E=-ΔV/Δs.
Or am I going in a completely wrong direction.
Homework Statement
A positive charge +q1 is located to the left of a negative charge −q2. On a line passing through the two charges, there are two places where the total potential is zero. The first place is between the charges and is 3.35 cm to the left of the negative charge. The second...
Homework Statement
Two objects are identical and small enough that their sizes can be ignored relative to the distance between them, which is 0.3 m. In a vacuum, each object carries a different charge, and they attract each other with a force of 2.3 N. The objects are brought into contact, so...
So I set that ratio equal to the ratio of vf/vi and then canceled out sqrt(\gammak/m) because it is constant in both cases therefore the ratio of Sinfθ/Siniθ is equal to sqrt(Tf)/sqrt(Ti) It was correct.

I had to draw out my own daigram. L1 is the distance from the feet to the cg, L2 is the distance from cg to the hand and X1 and X2 are just how I denoted distance in my notes, they're not given in the equations
So yes johnny you are correct.
