NEET Physics Question (2024) — Solution

Question

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

  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

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.
