A solid cylinder is rolling down an inclined plane without slipping. At any given instant, the velocity of the point of contact of the cylinder with the plane is:

  1. Equal to the velocity of the centre of the cylinder.
  2. Twice the velocity of the centre of the cylinder.
  3. Dependent on the inclination angle \( \theta \) and always positive.
  4. Zero.

Correct answer · Option 4

Zero.

Explanation

When a cylinder rolls down an inclined plane without slipping, the velocity of the instantaneous point of contact with the surface is zero.
