System of Particles and Rotational Motion

A wheel of a bullock cart is rolling on a level road as shown in the figure below. If its linear speed is in the direction shown, which one of the following options is correct ( and are any highest and lowest points on the wheel, respectively)?

Question 1 as printed in the NEET 2024 booklet

  1. A.Point P moves faster than point Q✓
  2. B.Both the points P and Q move with equal speed
  3. C.Point P has zero speed
  4. D.Point P moves slower than point Q

Solution

For a wheel rolling without slipping, the point of contact Q is momentarily at rest and the topmost point P moves at . So P moves faster than Q.
