MCQ

$Assertion$ : 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.

✓
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
C
If the Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

✓

Answer

Correct option: A.

If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

a
Under central force field, force acts along the line joining the bodies so it does not have rotatory effect i.e., torque is zero. Hence angular momentum is conservative
