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

Options

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

Answer

B

Explanation

As the particle is moving with constant angular velocity the tangential component of acceleration is ZERO.
Therefore only radial component `vec(a_(c))` is effective.
