The direction of the angular velocity vector is along

The direction of the angular velocity vector is along

Options

  1. Athe tangent to the circular path
  2. Bthe inward radius
  3. Cthe outward radius
  4. Dthe axis of rotation

Correct answer

D. the axis of rotation

Step-by-step solution

v (=r \times \omega). vv is the tangential. If rr is in the XYX Y plane and vv is also in this plane, (\omega) is in the ZZ direction. + or - is decided by whether the particle is rotating in the anticlockwise direction or clockwise direction.
