JEE Main 2016 (03 Apr)

Question

A particle of mass m is moving along the side of a square of side 'a', with a uniform speed υ in the x-y plane as shown in the figure:


Which of the following statements is false for the angular momentum L about the origin?

Choose an option

Show full solutionCorrect option: B
Correct answer
BL=mυ2Rk^

when the particle is moving from D to A.

Step-by-step explanation

L=r×P or L=rpsinθn^

For D to A, L=R2mv-k^

For A to B, L=R2mv-k^

For C to D, L=R2+amvk^

For B to C, L=R2+amvk^
