Which statement is true about the axis of rotation in pure rotational motion?
In pure rotational motion, the axis of rotation is fixed, meaning it does not move or change direction, constraining the body to rotate about it. As per NCERT, applying relevant law/formula with correct units and sign convention leads to It is always fixed. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
