Two particles P and Q are located at distance `r_(p) and r_(Q)` respectively form the centre of rotating disc such that `r_(P)gtr_(Q)`. The disc is rotating with constant angular acceleration. We can say

A

Both P and Q have the same acceeleration

B

Both P and Q do not have any accelcration

C

P has greater acceleration than Q

D

Q has greater acceleration than P

Text Solution

Verified by Experts

The correct Answer is:
C
Angular velocity of every particle of disc is same
`a_(r)= omega^(2) r_(p), a_(Q)= omega^(2)r_(Q)`
`:. r_(p) gt r_(Q) implies a_(p) gt a_(Q)`
