Assertion: For the purpose of calculation of moment of inertia, body's mass can be assumed to be concentrated at its centre of mass.
Reason: Moment of inertia of rigid body about an axis passing through its centre of mass is zero.
Reason: Moment of inertia of rigid body about an axis passing through its centre of mass is zero.
View answer and explanation
Correct option: D
If both Assertion & Reason are false
Option D is correct because the assertion that a body's mass can be concentrated at its center of mass for moment of inertia calculations is false, and the moment of inertia about the center of mass is not always zero.
