Question

A body of mass m is moving with a constant velocity along a line parallel to the x-axis, away from the origin. Its angular momentum with respect to the origin 

(a) is zero 

(b) remains constant 

(c) goes on increasing 

(d) goes on decreasing

Answer 1

Correct Answer is: (b) remains constant

Angular momentum with respect to the origin is equal to the product of the linear momentum and the perpendicular distance of the line of motion from the origin.
