Which of the following statements is FALSE for a particle moving in a circle with a constant angular speed ?

The acceleration vector points to the centre of the circle
The acceleration vector is tangent to the circle
The velocity vector is tangent to the circle
The velocity and acceleration vectors are perpendicular to each other.

Correct answer: The acceleration vector is tangent to the circle

Solution

The statement is false because, for a particle moving in a circle at constant angular speed, the acceleration vector, known as centripetal acceleration, always points towards the center of the circle, not tangentially along the path.
