In a bicycle the radius of rear wheel is twice the radius of front wheel. If rF and rr{r_F}\,and\,{r_r} are the radius, vF and vr{v_F}\,and\,{v_r}, are speeds of top most points of wheel, then
View answer and explanation
Correct option: C
vF=vr{v_F} = {v_r}
The correct answer is vF=vr{v_F} = {v_r} because the speeds of the topmost points of the wheels are equal to twice the speed of the bicycle, which is the same for both wheels.
