In circular motion of a particle is the velocity of particle always perpendicular to the centripetal acceleration?
Are there any exceptions?
Why or why not ?

Centripetal acceleration is straight towards the centre.
Meanwhile, velocity is always tangential to the path. You can therefore see the direction of velocity by drawing the tangent to the circle.
The tangient to a circle will at all points be perpendicular to the direction towards the centre.
So, yes, in circular motion the velocity is always perpendicular - And no, no exceptions.
