The angular acceleration of a body, moving along the circumference of a circle, is:

The angular acceleration of a body, moving along the circumference of a circle, is:
  1. along the axis of rotation
  2. along the radius, away from centre
  3. along the radius towards the centre
  4. along the tangent to its position

Solution

In terms of linear acceleration it is given as, a→=α→×r→. Clearly direction of linear acceleration is perpendicular to both angular acceleration and radius vector.

Angular acceleration of a body, moving along the circumference of a circle is along the axis of rotation.
