Homework Statement
This is a bit hard to describe without a decent picture (or a decent brain) but try to bare with me.
Picture below shows two spheres, if the origin is at centre of A, and a line d joins the centre of the two spheres, how do I describe the position of a point r from each sphere in spherical coordinates?
------------------r---------
A
------O---------------------
-----------------------------
-------------------O--------
B
Homework Equations
Polar coordinates are in terms of r and Ø
The point r described from the origin (at A) is given by (rA,ØA), where r is line from origin to point r.
The Attempt at a Solution
If origin was at B it would have coordinates (rB,ØB) need to write these in terms of rA and ØA.
I think rB=rA+d and Ø=ØB-ØA
