In uniform circular motion assuming vecV - Velocity,vec r= radius vect

1.	In uniform circular motion assuming vecV - Velocity,vec r= radius vector , vecomega= angular velocity relative to centre of the circle, veca= acceleration, which of the following is/are correct?
Answer» `\|DELTAVECV\| NE 0` but `Delta\|vecv\|=0` `\|Deltavecomega\|=0` and `Delta\|vecomega\|=0` `\|Deltavecr\| ne 0` but `Delta\|vecr\| = 0` `\|Deltaveca\| ne 0` but `Delta\|veca\| = 0` ANSWER :A
