The position of an object having mass 0.1 kg as a function of time t is given as $\vec{r}=\left(10 t^2 \hat{\mathrm{i}}+5 t^3 \hat{\mathrm{j}}\right) \mathrm{m}$. At $t=1 \mathrm{~s}$, which of the following statements are correct? A. The linear momentum $\vec{p}=(2 \hat{i}+1.5 \hat{j}) \mathrm{kg} \cdot \mathrm{m} / \mathrm{s}$. B. The force acting on the object $\vec{F}=(2 \hat{i}+3 \hat{j}) N$. C. The angular momentum of the object about its origin $\overrightarrow{\mathrm{L}}=15 \hat{\mathrm{~kJ}}$ D. The torque acting on the object about its origin $\vec{\tau}=20 \hat{\mathrm{k}} \mathrm{Nm}$. Choose the correct answer from the options given below :
