Questions
Two particles P and Q are located at distance respectively from the centre of rotating disc such that . The disc is rotating with constant angular acceleration. We can say
detailed solution
Correct option is C
Resultant acceleration,a = ar2+at2 = (ω2r)2+(rα)2⇒ a = r(ω2)2+α2As ω and α will be same for both the particles P and Q, hence aP>aQ(rp>rQ)Talk to our academic expert!
