Thank you. I know that dr = dr ir + dθ ir and that dr = dx ix + dy iy. How do I know in which situation to use each?

Homework Statement Suppose Coulomb's force is actually F= (y)(q1q2)(r hat)/(r^4) with y being a constant. Find the electric potential function V(x,y) for a charge Q located at the point x=a, y=b Homework Equations Fq=E V=integral (E)The Attempt at a Solution I am very confused by this...

why is D not a multiplet ?

sorry. what about now?

Homework Statement It asks you to identify the shift and nature of the protons in the molecule. Picture: https://mailhost-6.tamu.edu/service/home/~/?auth=co&id=24393&part=2 Homework Equations none The Attempt at a Solution I cannot understand what makes C a multiplet...

Oh I was overlooking that! Thank you so much, got the correct answer.

Thank you for replying. When I switch the charges, (3.28E-6)/(0.618+x)^2 + (1.07E-6)/(x)^2 = 0 I still get an imaginary answer. Edit: Is there a way to input math in an easier to read format on this forum?

Homework Statement Two fixed charges, +1.07 uC and -3.28 uC, are 61.8 cm apart. Where may a third charge be located so that no net force acts on it? Homework Equations Coulombs law The Attempt at a Solution q1 = 1.07 uC q2 = -3.28 uC q3 = q q1 ----- q2 ----- q q1 and q2...
