Question

write conservation law for angular momentum​

Answer 1

Answer:

Law of Conservation of Angular Momentum

→L=→l1+→l2+⋯+→lN=constant. ... Any of the individual angular momenta can change as long as their sum remains constant. This law is analogous to linear momentum being conserved when the external force on a system is zero.

Answer 2

$\huge\color{aqua}\boxed{ANSWER}$

The angular momentum of a system of particles around a point in a fixed inertial reference frame is conserved if there is no net external torque around that point:

dL⃗ dt=0

11.10

or

L⃗ =l⃗ 1+l⃗ 2+⋯+l⃗ N=constant.

11.11
