A wheel of radius r rolls without slipping with a speed v on a horizontal road. When it is at a point A on the road, a small blob of mud separates from the wheel at its highest point and lands at point B on the road.
- \(A B=\nu \sqrt{r / g}\)
- \(A B=2 v \sqrt{r / g}\)
- \(A B=4 v \sqrt{r / g}\)
- If \(v>\sqrt{4 r g}\), the blob of mud will land on the wheel and not on the road
Answer
(C) A B=4 v r / g
