Angular Momentum in CircleMediumQuestion 30628

Question

A particle moves in a circle of radius r at speed v. Its angular momentum about the centre has magnitude:
  1. A
    mvr
    Correct
  2. B
    mv/r
  3. C
    mv²r
  4. D
    mr²/v

Correct answer

mvr

Explanation

L = r × p = r × mv = mvr (for circular motion where r ⊥ v).
