Assertion : For a system of particles under central force field, the total angular momentum is conserved. Reason : The torque acting on such a system is zero.

Options:

Answer:

Solution:

When external torque acting on the system is zero then only the total angular mom entum of system is considered to be conserved. If $L = I ω =$ constant , $τ = I α = 0$ . $∴ α = \frac{d ω}{d t} = 0$ for constant $ω$ .
