The position vector $$\overrightarrow{r}$$ of a particle of mass m is given by the following equation 

$$\overrightarrow{r}(t) = \alpha t^3 \hat{i} + \beta t^2 \hat{j}$$
where $$\alpha = \frac{10}{3} ms^{-3}, \beta = 5 ms^{-2}$$ and m=0.1 kg. At t=1 s, which of the following statement(s) is(are) true about the particle?

The velocity $$\overrightarrow{U}$$ is given by $$\overrightarrow{U} = (10 \hat{i} + 10 \hat{j}) ms^{-1}$$

The angular momentum $$\overrightarrow{L}$$ with respect to the origin is given by $$\overrightarrow{L} = - \left(\frac{5}{3}\right) \hat{k} N ms$$

The force $$\overrightarrow{F}$$ is given by $$\overrightarrow{F} = (\hat{i} + 2 \hat{j}) N$$

The torque $$\overrightarrow{\tau}$$ with respect to the origin is given by $$\overrightarrow{\tau} = \left(\frac{20}{3}\right) \hat{k} Nm$$
