NEET 2024, Physics Q16: Rolling Motion

NEET2024Physics
Q.

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)?

  1. A

    Both the points P and Q move with equal speed.

  2. B

    Point P has zero speed.

  3. C

    Point P moves slower than point Q.

  4. D

    Point P moves faster than point Q.

Solution

For pure rolling, the contact point is instantaneously at rest (speed ).

The top point has speed (translation plus rotation at the top, adding in the same direction).

moves faster than .
