M2 Work, Energy and Power

In the pds there is a question and my workings, which are incorrect as the answer is root(2ga/3).

I'm stuck again. Help, please.

The problem is with your diagram, though the wording of the question doesn't help. The point O is on the rod, a distance "a" from A, i.e. the mid-point.
