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

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

Solution & Step-by-step Explanation

In uniform circular motion (constant angular speed):The velocity is always tangential to the path. (Option A is true)There is no tangential acceleration because speed is constant.The only acceleration is centripetal acceleration, which points toward the center. (Option C is true, Option B is false)Since velocity is tangential and acceleration is radial, they are perpendicular. (Option D is true)
