Let R be an equivalence relation on a set S. Let E and F be two distinct equivalence classes of R. Prove that E and F = null set.

Do i show that itys transitive im a bit stuck. Help much appreciated thanks.

More of a forward-knowledge looking back approach (since you need to do this problem to prove what I'm about to say), but a relation on induces a partition of where the blocks are the equivalence classes. If that is a definition in your book the answer follows immediately.
