A rod of mass M and length L is initially vertical and is hinged about a point $P$. The point $P$ moves horizontally with acceleration equal to $g$, where $g$ = Earth's gravitational pull . Find the $x$-component and $y$-component of the reaction force on $P$ at the instant when the rod is horizontal.
