In uniform circular motion, which of the following statements is wrong?

For a particle in uniform circular motion,the acceleration $\vec{a}$ at a point $P(R, \theta)$ on the circle of radius $R$ is (Here $\theta$ is measured from the $x$-axis):

If $\vec{L}$ and $\vec{P}$ represent the angular momentum and linear momentum respectively of a particle of mass $m$ having position vector $\vec{r} = a(\hat{i} \cos \omega t + \hat{j} \sin \omega t)$,the direction of the force acting on the particle is:

If the kinetic energy $(KE)$ of a particle of mass $m$ performing uniform circular motion $(UCM)$ in a circle of radius $r$ is $E$,find the acceleration of the particle.

If a particle moves in a circle describing equal angles in equal times,its velocity vector

$A$ particle is moving in a circle with uniform speed. Its motion is
