An annular ring with inner and outer radii `R_1` and `R_2` is rolling wihtout 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, `F_1/F_2` is

Options

A. (a) `((R_1)/(R_2))^2`
B. (b) `R_2/R_1`
C. (c) `R_1/R_2`
D. (d) 1

Answer

C

Explanation

Force experienced by the particle, `F=momega^2R`
`:.` `F_1/F_2=R_1/R_2`
