The acceleration vector is tangent to the circle.

Vedclass · Answer

(B) In uniform circular motion,the speed of the particle is constant,but the direction of velocity changes continuously. The velocity vector is always tangent to the circular path at any point. The acceleration in uniform circular motion is centripetal,meaning it is directed towards the center of the circle. Since the velocity is tangent and the acceleration is radial (towards the center),they are always perpendicular to each other. Therefore,the statement that the acceleration vector is tangent to the circle is incorrect.
