In a bicycle, the radius of the rear wheel is twice the radius of front wheel. If $r_{F}$ and $r_{F}$ are the radii, $v_{r}$ and $v_{r}$ are the speed of top most points of wheel. Then :

v_{r} = 2 v_{F}

Solution

The correct option is A $v_{f} = v_{r}$
The topmost points of both the wheels must have same velocity as that of the bicycle so that the system will move as a whole but the wheels can have different angular velocities.
