Globular clusters cylindrical polar coordinates

  1. Jan 10, 2010 #1
    1. The problem statement, all variables and given/known data

    Two globular clusters A and B have cylindrical polar coordinates relative to the centre of the galaxy (r, z, Ø) given by A = (5,2,15°) and B= (4.6,65°), where the r and z coordinates are in kiloparsecs.

    2. Relevant equations

    Find a and b the position vectors of each globular cluster relative to the centre of the galaxy, in terms of the cartesian unit vectors i, j, k.

    Hence find the vector displacement of B relative to A and the seperation in kiloparsecs of the globular clusters


    3. The attempt at a solution

    Im lost and am not sure where to start.
