A mass ' M ' is moving with constant velocity parallel to X -axis. Its angular momentum with respect to the origin is (a) constant (b) zero (c) decreasing (d) increasing

Answer: (a). L = mvd, where d is the perpendicular distance of the line of motion from the origin. v is constant and the line is parallel to the X-axis, so d is fixed. So L is constant: answer (a).

Angular Momentum & its Conservation

A mass ' $M$ ' is moving with constant velocity parallel to $\mathrm{X}$ -axis. Its angular momentum with respect to the origin is

Show answer and solution

Answer: (a)

$L = mvd$ , where $d$ is the perpendicular distance of the line of motion from the origin.
$v$ is constant and the line is parallel to the X-axis, so $d$ is fixed.
So $L$ is constant: answer (a).
