# Globular clusters cylindrical polar coordinates

## Homework Statement

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.

## Homework 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
