NEET2024PhysicsRotational MotionActual
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)?
Options
- APoint P moves faster than point Q
- BBoth the points P and Q move with equal speed
- CPoint P has zero speed
- DPoint P moves slower than point Q
Correct answer
A. Point P moves faster than point Q
Step-by-step solution
In the case of pure rolling, The topmost point will have velocity 2 v while point Q i.e. lowest point will have zero velocity. Hence point P moves faster than point Q .
