JEE MAIN - Physics (2004 - No. 71)
Which of the following statements is FALSE for a particle moving in a circle with a constant
angular speed?
The velocity vector is tangent to the circle.
The acceleration vector is tangent to the circle.
The acceleration vector points to the centre of the circle.
The velocity and acceleration vectors are perpendicular to each other.
Explicación
Only option $$(b)$$ is false since acceleration vector acts along the radius of the circle or towards center of the circle for uniform circular motion and velocity vector always acts along the tangent of the circle.
