Small bead - Circular loop Problem

[Albinjijo]

Homework Statement

A small bead is fixed on a circular loop of radius R as shown in the figure below. The
loop is rotating about YY axis with constant angular acceleration ‘α’. The loop starts
from rest, then, the bead is in circular motion, then acceleration of the bead at instant
‘t’ is_______.

Relevant Equations

Hello. Welcome to PF!

Homework Statement: A small bead is fixed on a circular loop ...

If I'm interpreting the problem correctly, then the bead cannot slide along the loop. It is fixed at point P. So, I think this is just a kinematics problem. No need to consider forces.
