An annular ring with inner and outer radii R1 and R2 is rolling without slipping with a uniform angular speed.
An annular ring with inner and outer radii R1 and R2 is rolling without slipping with a uniform angular speed. The ratio of the forces experienced by the two particles situated on the inner and outer parts of the ring, F1 /F2 is
(a) 1
(b) R1/R2
(c) R2/R1
(d) (R1/R2)2

(b) : Centripetal force on particle = mRω2
Therefore, F1/F2 = (mR1ω2)/(mR2ω2)= R1/R2.
