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.

Hi Pratyush, and welcome to Physics Stack Exchange! This is a site for conceptual physics questions, not a place to get people to do your homework for you. If you'd like to edit this to ask about the concept that is giving you trouble, it can be reopened. See our homework policy for more information. – David Zaslavsky♦ Jan 25 at 5:20
