A uniform rod of mass `m` is supported on two rollers each of mass `m//2` and radius `r` and rolls down the inclined rough plane as shown in the figure. Assuming no slipping at any contanct and treating the rollers as uniform solid cylinders:

If the friction force on roller at the contanct point with incline is `f_(1)` and at the contact point with rod is `f_(2)` then:

Options

A. `f_(1)gtf_(2)`
B. `f_(1)ltf_(2)`
C. `f_(1)=f_(2)`
D. data is insufficient to decide

Answer

A
