Question

If a particle of mass m is moving in horizontal uniform circular motion, then the angular momentum of the particle is constant about

• A. radius of the circle
• B. center of the circle
• C. tangent of the circle
• D. None of the above

Answer 1

Answer: (B)

Since, angular momentum is an axial vector, hence, for uniform circular motion in a horizontal plane the angular momentum remains constant about the center of circle
