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 )`

Options

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 )`

Answer

B
