Three identical solid spheres move down ...

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

A

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

B

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

C

`E_(A) gt E_(B) gt E_(C )`

D

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