Three identical solid spheres moves down three incline A, B and C-all of the same dimensions . A is without friction, the friction between B and sphere is sufficient to cause rolling without slipping, the friction between C and sphere causes rolling with slipping. The kinetic energies A,B,C at the bottom of the inclines are E_(A), E_(B), E_(C )

Answer»

`E_(A)=E_(B)-E_(C )`
`E_(A)=E_(B) GT E_(C )`
`E_(A) gt E_(B) gt E_(C )`
`E_(A) gt E_(B) = E_(C )`

ANSWER :B
