Vedclass · Answer

(C) $1$. Option $A$ is correct: $	au = I \alpha$,which is the rotational analogue of Newton's second law $(F = ma)$.$2$. Option $B$ is correct: $	au = p 	imes B$ (or $\mu 	imes B$),representing the torque on a dipole in a magnetic field.$3$. Option $C$ is incorrect: The correct relation is $I = \frac{	au}{\alpha}$. The given relation $I = 	au 	imes \alpha$ is dimensionally and physically wrong.$4$. Option $D$ is incorrect: The correct relation for angular momentum is $L = I \omega$. Linear momentum is $p = mv$. The relation $p = I \omega$ is physically incorrect.Note: Since the question asks for the incorrect relation and both $C$ and $D$ are incorrect,$C$ is the most fundamental error in rotational dynamics definitions.
