Angular momentum

Question

A particle moves on a straight line with a uniform velocity. The incorrect statement about its angular momentum

Moderate

A

is always zero
B

is zero about a point on the straight line
C

is not zero about a point away from the straight line
D

about any given point remains constant.

Solution

Angular momentum of the particle about point A, L = mv x r. If A lies on the line of motion r = 0 then only L = 0. so option (1) is wrong.
