good one

a rod is aligned at a corner as in figure. no friction is there anywhere. it start to slide. prove that it would leave the vertical wall when it's tip is at a height 1/3rd of initial.

edit:: the actual question asked 1/3rd height fallen or "leave the vertical wall when it's tip is at a height 2/3rd of initial". my question was wrong previously...
