Assertion : The moment of Linear Momentu...

Assertion : The moment of Linear Momentum is called Angular momentum (L) i.e.
`L = r xx p = (mv) xx r = mvr`
if V = `r omega` then.
`L = mr^(2) omega (or) L = I omega`
Reason : For conservation of Angular momentum, Torque (Rotational force applied externally) must be zero.

A

Assertion and Reason are correct and Reason is correct explanation of Assertion

B

Assertion and Reason are true but Reason is the false explanation of the Assertion

C

Assertion is true but Reason is false
