Question

if not external force acting on the system of particles is zero which of the following quantities remains conserved a) linear momentum b) angular momentum c) both linear and angular momentum d) neither linear nor angular momentum ​

Answer 1

Answer:

a linear momentum

Explanation:

as Fext =dp/dt

0=dp/dt

..change in linear momentum is zero..that means its conserved.

☆angular momentum will be conserved when net torque on the system is zero

Ť=dL /dt

hope it helps..
