An annular ring with inner and outer radii R_(1) and R_(2) is rolling without slipping with a uniform angular speed. The ratio of force experienced by the two particles situated on the inner and outer parts of the ring. (F_(1))/(F_(2)) = …………

Answer»

`(R_(1))/(R_(2))`
1
`((R_(1))/(R_(2)))^(2)`
`(R_(2))/(R_(1))`

Solution :The centripetal force due to rolling ring,
`(mv^(2))/(R )=F`
`therefore (MR^(2)OMEGA^(2))/(r)=F`
`therefore F=mromega^(2)`
`therefore F_(1)=mR_(1)omega^(2)`
`therefore F_(2)=mR_(2)omega^(2)`
`therefore (F_(1))/(F_(2))=(R_(1))/(R_(2))`
