A particle of mass `M` may move with the velocity `v`, along `AO`, or `DE` or `BC`. Then which of the following statements is not correct about particle's angular momentum about point `O`.
.

Options

A. It is zero when it is at `A` andmoves along `OA`.
B. It is same at all points along the line `DE`
C. It is of the same magnitude but oppositely directed `B` and `D`.
D. It increases as it moves along the line `BC`.

Answer

D

Explanation

(d) When particle moves along `BC`, its angular momentum will remain same about `O`, as its perpendicular disatance remains same.
