A particle m starts with zero velocity along a line y = 4d. The position of particle m varies as x = A sinωt. At ωt = π/2, its angular momentum with respect to the origin

Q: A particle of mass m starts with zero velocity along a line y = 4d. The position of particle m varies as x = A sinωt. At ωt = π/2 , its angular momentum with respect to the origin
(A) mAωd
(B) mωd/A
(C) mAd/ω
(D) zero
Sol:
rotation
At ωt = π/2
x = A sinωt
v = Aωcosωt = 0
So, angular momentum of particle m with respect to the origin should be zero.
