Question

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

विकल्प

• 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.

Answer 1

The acceleration vector is tangent to the circle. 

Explanation:

Only option (b) is false because uniform circular motion always has an acceleration vector that is radial, or moving towards the centre.
