Physics · MOTION IN A PLANE

हिन्दी

Consider the following statements regarding uniform circular motion: (A) The speed of the particle remains constant. (B) The velocity vector of the particle continuously changes. (C) The centripetal acceleration vector is directed tangentially to the circle. (D) The magnitude of centripetal acceleration is given by \( \omega^2 R \). Which of the above statements are correct?

  1. (A), (B) and (D) only
  2. (A) and (C) only
  3. (B) and (C) only
  4. (A), (B), (C) and (D)

Correct answer · Option 1

(A), (B) and (D) only

Explanation

(A), (B), and (D) are true statements. Statement (C) is incorrect because centripetal acceleration is directed radially inwards towards the center, whereas velocity is tangential.
