Hi, 

I have to prove an equation and I'm having trouble. I have to de-compose vectors from an electric dipole to prove the value of the electric field of a dipole on a bisecting plane as such:

Where p is the dipole moment, so p = qs.

Since the x-value of the fields of the two charges negate themselves, I only want the Y values right?

So I put the value of each field in a "sin", and I'm stuck from there...:

Hi,

Is this it?

thanks!

Hi,

I need help for problem 14. I don’t understand how to compare the second equation to the first so that I can answer in terms of F.

Thank you.
