Rotational Motion question

2016 · Shift 0 · Q44

JEE MainPhysicsRotational MotionMultiple correct+4 / −1
A particle of mass m is moving along the side of a square of side ‘a’, with a uniform speed v in the x-y plane as shown in the figure : JEE Main 2016 (Offline) Physics - Rotational Motion Question 192 English Which of the following statements is false for the angular momentum L→\overrightarrow LL about the origin ?
  1. A
    L→=mv[R2+a]k^\overrightarrow L = mv\left[ {{R \over {\sqrt 2 }} + a} \right]\widehat kL=mv[2​R​+a]k when the particle is moving from B to C.
  2. B
    L→=mv2Rk^\overrightarrow L = {{mv} \over {\sqrt 2 }}R\widehat kL=2​mv​Rk when the particle is moving from D to A.
  3. C
    L→=−mv2Rk^\overrightarrow L = - {{mv} \over {\sqrt 2 }}R\widehat kL=−2​mv​Rk when the particle is moving from A to B
  4. D
    L→=mv[R2−a]k^\overrightarrow L = mv\left[ {{R \over {\sqrt 2 }} - a} \right]\widehat kL=mv[2​R​−a]k when the particle is moving from C to D.
