Physics · SYSTEMS OF PARTICLES AND ROTATIONAL MOTION

हिन्दी

When a rigid body rotates about a fixed axis, which of the following is true for a particle located directly on the axis of rotation?

  1. It moves in a circle of maximum radius.
  2. It remains stationary as its distance \( r \) from the axis is zero.
  3. It performs simple harmonic motion along the axis.
  4. It moves with the maximum linear acceleration.

Correct answer · Option 2

It remains stationary as its distance \( r \) from the axis is zero.

Explanation

For any particle located on the fixed axis of rotation, \( r = 0 \), and hence it remains stationary while the body rotates.
