Assertion: If linear momentum of a particle is constant, then its angular momentum about any point will also remain constant. Reason: Linear momentum remains constant if F_(n et)=0 and angular momentum remains constant if tau_(n et)=0

Assertion : A body is moving along a circle with a constant speed. Its angular momentum about the centre of the circle remains constant Reason : In this situation, a constant non-zero torque acts on the body.

A solid sphere is rotating with a constant angular velocity about an axis touching the surface. Its angular momentum will be:

Assertion : In planetary motion angular momentum of planet about centre of sun remains constant. But linear momentum of system does not remain constant. Reason : Net torque on planet any point is zero.

A particle is moving in a horizontal uniform circular motion. The angular momentum of the particle is conserved about the point :
