A wheel of a bullock cart is rolling on a level road as shown in the figure below. If its linear speed is v in the direction shown, which one of the following options is correct (P and Q are any highest and lowest points on the wheel, respectively)?
Point P moves slower than point Q
Point P moves faster than point Q
Both the points P and Q move with equal speed
Point P has zero speed
Point P moves faster than point Q
In the case of pure rolling,
The topmost point will have velocity 2v while point Q i.e. lowest point will have zero velocity. Hence point P moves faster than point Q.
