Question
Two particles P and Q are located at distances rP and rQ respectively from the axis of a rotating disc such that rP > rQ :
Options
A.Both P and Q have the same acceleration
B.Both P and Q do not have any acceleration
C.Both P and Q do not have any acceleration
D.Q has greater acceleration than P
Solution
Angular velocity of every particle of disc is same
aP = ω2rp , aQ = ω2rQ
∵ rP > rQ ⇒ aP > aQ Ans.
aP = ω2rp , aQ = ω2rQ
∵ rP > rQ ⇒ aP > aQ Ans.
