Five objects of mass m move at velocity 
At a distance r from an axis of rotation perpendicular to the page through point A,as shown below.The one that has zero angular momentum about that axis is

Quizplus · Accepted Answer

The formula for angular momentum is L = r x p, where r is the vector representing the distance between the axis of rotation and the object, and p is the object's momentum. 
Since all objects have the same mass and velocity, the only factor that determines their angular momentum is their distance from the axis of rotation. The object closest to the axis of rotation will have the smallest angular momentum, which is D) 11ea7ff9_2b2e_7350_a768_abd85730fe84_TB2295_11.
