Hi Donut Mulitply both sides through by $\displaystyle r^2$ you can then use the quadratic formula to solve for r.
hmm thats what I thought I should do but I get keep getting this obscenely small number. Back to the drawing board I guess >_< Thanks for the reply I might post up all my previous working in a sec and see if someone can see the holes in it.
Are the calculations right?
If I can find out that all the above maths is correct it would be a massive help
Take your solutions for r and sub them into the RHS of the equation. Does it give you the LHS?
