A particle of mass 'm' is attached to the rim of a uniform disc of mass 'm' and radius R. The disc is rolling wihtout slipping on a stationery horizontal surface as shown in the figure. At a particular instant, the particle is at the topmost position and centre of the disc has speed `v_(0)` amd its angular speed is `omega`. Choose the correct option (s).

A

`v_(0)=omegaR`

B

kinetic energy of the system is `(11)/(4) mv_(0)^(2)`.

C

speed of point mass m is less than `2v_(0)`

D

`|v_(C)-v_(B)|=|v_(B)-v_(D)|`
