NEET (UG) 2024 — Question 2

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)?

Question figure

Option A:
Point $P$ moves slower than point $Q$
Option B:
Point $P$ moves faster than point $Q$
Correct
Option C:
Both the points $P$ and $Q$ move with equal speed
Option D:
Point $P$ has zero speed

Answer: B

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 $Q$ .
