#### A mass M is moving with a constant velocity parallel to the X-axis. Its angular momentum with respect to the origin Option 1) Is zero Option 2) Remains constant Option 3) Goes on increasing     Option 4) Goes on decreasing

As we discussed in

Law of conservation of angular moment -

- wherein

If net torque is zero

i.e.

angular momentum is conserved only when external torque is zero .

No-change

Option 1)

Is zero

incorrect

Option 2)

Remains constant

correct

Option 3)

Goes on increasing

incorrect

Option 4)

Goes on decreasing

incorrect
