Solution

The correct option is C


The tangential acceleration due to angular acceleration α=αR

The normal (centripetal acceleration) = ω2R

Net acceleration

=α2R2+ω4R2

=(α2+ω4)R

[Note that velocity v of the centre of mass has no effect on the acceleration of P, this is because it is a constant]
