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
