Question 182 of 183

An annular ring with inner and outer radii R1R_1 and R2R_2 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/F2F_1 / F_2 is

Show answer and solution

Answer: (D) R1R2\frac{\mathrm{R}_1}{\mathrm{R}_2}

F1 F2=R1ω2R2ω2=R1R2\frac{\mathrm{F}_1}{\mathrm{~F}_2}=\frac{\mathrm{R}_1 \omega^2}{\mathrm{R}_2 \omega^2}=\frac{\mathrm{R}_1}{\mathrm{R}_2}
