Which of the following are correct expression for torque acting on a body? A.

\vec{\tau} = \vec{r} \times \vec{L}

\vec{\tau} = \frac{d}{dt}(\vec{r} \times \vec{p})

\vec{\tau} = \vec{r} \times \frac{d\vec{p}}{dt}

\vec{\tau} = I\vec{\alpha}

\vec{\tau} = \vec{r} \times \vec{F}

(

\vec{r}

= position vector;

\vec{p}

= linear momentum;

\vec{L}

= angular momentum;

\vec{\alpha}

= angular acceleration;

I

= moment of inertia;

\vec{F}

= force;

t

= time) Choose the correct answer from the options given below:
